Modest Swimwear: Every Level of Coverage, and How It Holds Up in the Water

What Counts as Modest Swimwear

Ask ten people what modest swimwear means and you will get ten answers. For one person it is a one-piece with a higher neckline instead of a bikini. For another it is a suit that covers the elbows and knees. For another it is loose, full-length coverage that includes the hair. All of them are modest swimwear; they simply cover different zones.

Most people land on a combination rather than a single item. A tankini top with swim shorts covers the midriff and thighs while leaving the arms free. A long-sleeve swimsuit covers the arms and torso but stops at the hip. A rash guard over a swim dress with leggings covers almost everything. Decide which zones matter to you, then choose the pieces that cover them.

There is also a seventh consideration that is not a body zone at all: how close the fabric sits to the body. A fitted long-sleeve suit covers the arms but still shows their shape. Some traditions and some people prefer looser cuts that do not trace the body, which usually means a longer tunic top, a swim dress or a burkini. Loose cuts give the most coverage of shape, and they are also the hardest to swim in, a trade-off we come back to below.

The setting changes the answer too. Someone who wears a standard one-piece at a hotel pool may want sleeves and shorts at a family water park, a church camp or a beach in a conservative country. It is common to own pieces from more than one level and combine them: a long-sleeve rash guard pulled over a tankini, or swim shorts added under a swim dress. Separates make that easy, which is one reason tankinis and swim bottoms sell so well in modest ranges.

The Modest Swimwear Coverage Ladder

The ladder is not a ranking of good and bad, just of how much each style covers. A high-waisted bikini is a reasonable choice for someone who wants the navel and lower stomach covered and nothing more; our guide to the high-waisted bikini covers how the rise works. A burkini is the right choice for someone who wants the hair, arms and legs covered. Most people sit somewhere in the middle, and many own two or three pieces from different rungs for different settings: a tankini for the hotel pool, a long-sleeve suit for snorkeling, a swim dress for the beach.

Three rungs of the ladder: a tankini with a swim skirt, a long-sleeve high-neck one-piece and a swim dress with attached shorts.

Modest Swimwear Styles, One by One

Tankinis

A tankini pairs a tank-style top that covers the midriff with a separate bottom. It is the most popular modest style for a reason: it feels like an ordinary swimsuit, it lets you choose the top and bottom in different sizes, and it makes bathroom trips easier than a one-piece. Paired with a full brief, a swim skirt or swim shorts, it covers everything from the chest to the seat or thigh. The weak point is the hem of the top, which can float up in the water; a longer top, a top that tucks into a high-waisted bottom or a fitted band at the hem keeps it in place. Our tankini guide explains how to stop the top floating up, and HauteFlair tankinis include underwire, crossover and high-neck tops.

Swim dresses

A swim dress is a one-piece with a skirt panel attached, usually over a built-in brief or short. It covers the hips and the top of the thighs, which is why it is a favorite for people who want the seat covered without wearing shorts. The skirt is the trade-off: it floats as you enter the water and adds drag when you swim. A skirt that ends at mid-thigh, a fitted brief underneath and a heavier fabric all help. Our swim dress guide goes into skirt length and the attached brief in detail.

Swim skirts and swim shorts

Swim skirts and swim shorts are bottoms, worn with a tankini top or over a one-piece. A swim skirt usually has a brief or short sewn inside; swim shorts look like board shorts or bike shorts made in swim fabric. Shorts are the more practical choice for active swimming and water parks, because they cannot lift. Skirts give a looser line over the hips. Our guides to the swim skirt and to swim shorts compare lengths and waistbands.

High-neck and long-sleeve one-pieces

A one-piece with a higher neckline covers the chest fully and stays put when you dive, which a low scoop may not. Adding sleeves, from cap sleeves to full length, covers the shoulders and arms. A long-sleeve swimsuit is one of the most practical modest styles: it swims like an ordinary one-piece, covers most of the upper body and protects the skin from sun. Many come with a front zip, which makes them easier to put on and lets you adjust the neckline. One-piece swimsuits at HauteFlair include higher-neck and fuller-coverage cuts.

Skirted and short-leg one-pieces

Between the one-piece and the swim dress sits a group of suits with a little extra built in: a short skirt panel across the front, a boy-short leg that reaches the top of the thigh, or a ruched side panel that adds fabric over the hips. They give more coverage of the seat and hips without the drag of a full skirt, and they look like an ordinary swimsuit from a distance. They suit people who want slightly more coverage than a one-piece for active swimming but find a swim dress too loose in the water.

Rash guards and swim leggings

A rash guard is a fitted swim top with sleeves, first worn by surfers to protect the skin from board rash and sun. Swim leggings are full-length or capri tights made in swim fabric. Worn together over a swimsuit, or over a swim dress, they cover nearly the whole body while staying close enough to the skin to swim freely. Because they are fitted, they show the body's shape more than a loose tunic does, so some people add a swim skirt or a longer top over them.

Burkinis

A burkini is a full-coverage swimsuit, usually in two or three pieces: a long tunic top with sleeves, full-length swim trousers and a fitted hood that covers the hair. It was designed by Australian designer Aheda Zanetti in the mid-2000s so that Muslim women and girls could swim and take part in water sports, and Burqini and Burkini are trademarks of her company, although the word is now used for full-coverage swimwear in general. A burkini is made in swim fabric, not ordinary clothing fabric, so it dries quickly and can be worn in most pools. The tunic is cut looser than a rash guard, which covers the shape of the body as well as the skin.

Swim hijabs and swim caps

A swim hijab is a fitted head covering made in swim fabric, often in one piece with a neck panel, so it stays in place when wet. Some people wear one with a burkini; others pair one with a long-sleeve swimsuit and leggings. A swim cap covers the hair too, though it is designed to keep hair dry and reduce drag rather than for modesty. Whatever covers the hair should be made for water, because an ordinary scarf becomes heavy and slips when soaked.

Dry Coverage Is Not Wet Coverage

Skirts float. Any loose hem, whether a swim dress skirt, a swim skirt or a long tunic, lifts as you step into the water and drifts upward around you. A built-in brief or short underneath means nothing shows when it does. Shorter skirts float less than long ones, and heavier fabric floats less than light fabric.

Light colors turn sheer. Wet fabric lets more light through, and white, pale and pastel colors show it most. A full lining, a darker color or a print, and a heavier knit all keep a suit opaque. Hold the fabric to a window before you buy; if you can see your hand through a single layer, it will show more when wet.

Necklines gap. A neckline that sits flat when you stand can fall forward when you bend, dive or climb a ladder. Higher necks, crossover fronts, a fitted band under the bust and adjustable straps all reduce gaping. Bend forward in front of a mirror before you commit.

Loose fabric balloons. Air and water collect inside loose tunics and wide sleeves, so they puff out when you enter the water and cling when you leave it. Fitted cuffs, a fitted inner layer and fabric with some weight help. This is the main reason burkini tunics and swim dresses often have a fitted layer underneath.

You can test most of this at home before the tags come off. Wet a corner of the lining under a tap and hold it to a window to see how much light passes through. Put the suit on and bend forward, sit cross-legged and raise both arms above your head in front of a mirror. Check that a tankini top still meets the bottom and that the brief under a skirt covers you on its own. If something gaps or rides up dry, it will do so more in the water.

Swimming in More Fabric

Every extra layer of fabric adds some drag and holds some water. The important difference is between fitted and loose. A fitted long-sleeve suit or rash guard with leggings moves with the body, so it adds little drag and drains quickly. A loose tunic or a full skirt catches water like a sail, adds weight when you climb out and takes longer to dry.

That does not mean loose styles cannot be swum in. Many people swim comfortably in burkinis and swim dresses. It means matching the style to what you will actually do in the water: a loose cut is fine for wading, playing with children and floating, while lap swimming and snorkeling go better in fitted pieces.

Two practical points help in the water. First, wet fabric weighs more, so a heavy tunic or a long skirt pulls down on the shoulders when you climb out; wide straps and a fitted bodice spread that weight. Second, more fabric takes longer to dry, so a full-coverage set worn for a morning swim may still be damp at lunch. Quick-dry polyester blends and a second suit for the afternoon both help on a beach vacation.

Water parks deserve a special mention. Many have their own rules for slides, often banning loose ties, buckles, zips and long loose garments that can catch or slow a rider down. Fitted pieces such as swim shorts, leggings and a rash guard are usually accepted on slides, while a long skirt or tunic may not be. If you plan to use the slides, check the park rules and bring a fitted option.

Fabric, Lining and Sun Protection

Elastane, also sold as spandex or Lycra, is what makes swimwear stretch, and it is also what chlorine damages first. A suit with a high elastane content will feel wonderful at first and slowly lose its shape if you swim in chlorinated pools several times a week. Polyester-rich fabrics, including PBT, hold their shape and color much longer in chlorine. If you swim mostly in the sea or on vacation, ordinary nylon and spandex is fine; if you swim laps weekly, look for a chlorine-resistant label.

Lining is the other half of opacity. A fully lined suit has a second layer of fabric behind the front, and often the back, which keeps it opaque when wet and gives a smoother surface. Front-only lining is common and fine in darker colors. An unlined pale suit is the one most likely to turn sheer in the water.

Sun protection is a real advantage of modest swimwear. Fabric is rated by UPF, its ultraviolet protection factor. A fabric rated UPF 50 lets through about one fiftieth of the UV that reaches it, blocking about 98 percent. Covered skin needs no sunscreen, which is why long sleeves and leggings are popular with swimmers, surfers and parents who spend long hours outside. Not every suit is tested and rated, so look for the rating on the label if sun protection matters to you, and remember that stretching fabric thins it and can lower its protection.

Texture helps more than people expect. A rib knit, a crinkle or seersucker texture, or a jacquard pattern breaks up the surface, so it hides the outline of what is underneath better than a smooth, shiny fabric of the same weight. Matte fabrics also show less of the body's shape when wet than glossy ones. Chlorine fades color as well as elastic, so bright solids lose their depth fastest in heavily treated pools, while prints and darker colors hide fading longer.

Modest Swimwear in Faith and Tradition

Modest swimwear is worn for many reasons: religious observance, cultural custom, sun protection, comfort, body confidence or simply preference. When faith is the reason, the guidance you follow will come from your own community and tradition, and practice varies widely. What follows describes common patterns so you can see how different styles fit different expectations.

Whatever the reason, the same practical points apply. Choose swim fabric rather than ordinary clothing, make sure the pieces stay in place wet, and check the pool or beach rules if you plan to wear a full-coverage set. If you are buying for a particular community or event, such as a women-only swim session or a school trip, ask what is expected before you buy; it saves guesswork and returns.

Bust Support in Modest Swimwear

Many modest suits rely on a simple shelf bra: a band of elastic and a layer of lining under the bust. That works for smaller cup sizes but offers little lift or separation for fuller busts, and it can leave a high neckline looking flat. If you wear a D cup or larger, look for underwire, molded cups or a suit sold in bra sizes rather than dress sizes.

Tankinis make this easier, because the top is bought separately and many are built like a bra: underwire, adjustable straps and a hook back. A long-sleeve suit or tunic can be worn over a supportive swim bra or tankini top. Our guide to bra-sized swimwear explains how cup sizing changes the fit, and bra-sized swimwear at HauteFlair includes underwire tankini tops with higher necklines.

Higher necklines change how support looks as well as how it feels. A high neck or crew neck covers the cleavage completely, so the shape of the bust is defined by the cups underneath; molded or lightly padded cups give a smooth, rounded line, while a shelf bra alone can flatten. Crossover and twist fronts are a good middle ground, giving coverage and some shaping without a high neck that feels tight around the throat.

Plus Size Modest Swimwear

Plus size modest swimwear covers the same range as straight sizes, from tankinis and swim dresses to long sleeves and full-coverage sets. The details worth checking are the ones that are easy to get wrong when a pattern is simply scaled up: strap width, bust support, the length of the tankini top and the coverage of the brief at the back.

A tankini that is long enough to meet the bottom with some overlap, a swim dress with a fitted brief underneath and wide, adjustable straps make the biggest difference. Many people also like a suit with a tummy control panel, which smooths the front without adding bulk; our guide to tummy control swimsuits explains what the panel actually does. Browse plus size swimwear and tummy control swimsuits for fuller-coverage styles.

How to Choose Modest Swimwear

Size for the wet fit, not the dry one. Swim fabric relaxes slightly in water, so a suit that feels snug dry usually feels right wet, and a suit that feels comfortable dry can feel loose once it is soaked. Tankini tops should overlap the bottom by at least a couple of inches with your arms raised. Swim skirts and dresses should have a brief or short that fits closely on its own, without relying on the skirt to cover it.

Separates are the easiest way to get the fit right. Many people wear a different size on top and bottom, and modest separates let you buy each in its own size: a tankini top sized for the bust, swim shorts sized for the hips. They also let you change the coverage for the day, adding shorts for a water park or a skirt for the beach, without buying a whole new suit.

Public Pools, Beaches and Travel

Most public pools, gyms and hotels ask for proper swimwear, which in practice usually means swim fabric rather than cotton, denim or street clothes. Burkinis, rash guards and swim leggings made in swim fabric meet that rule in most places, because they are swimwear. Problems usually come from cotton T-shirts, leggings made for the gym or long loose garments in clothing fabric, which absorb water and can be unsafe in the pool.

Rules do vary. Some pools in Europe have restricted loose garments or full-body suits, and in 2016 several French seaside towns tried to ban the burkini on their beaches, a ban that France's highest administrative court suspended in one town that August. If you are traveling, check the pool or resort rules before you go, and pack a fitted alternative such as a long-sleeve suit with leggings, which is accepted almost everywhere.

For travel generally, a modest wardrobe packs easily if it is built from separates: one or two tankini tops, a swim skirt and swim shorts, and a rash guard can be combined in several ways. A light cover-up for walking from the beach to a cafe completes it; our guide to kaftans, sarongs and beach cover-ups explains which suits which setting.

Cover-ups for modest swimwear

A cover-up extends the coverage of any suit out of the water. A long kaftan or a maxi-length beach dress covers everything for the walk to a cafe or a hotel lobby; a sarong tied at the waist covers the hips and thighs over a tankini; a lightweight long-sleeve shirt covers the arms. Choose a fabric that dries fast and does not cling, such as cotton voile, linen or a light rayon, so it can go straight over a damp suit.

Caring for Modest Swimwear

Rinse, wash gently and dry flat in the shade. A wet skirt or tunic hung by its straps stretches under its own weight.

A Short History of Modest Swimwear

In the nineteenth century, women who bathed at the seaside wore bathing dresses of wool or flannel with bloomers or stockings underneath, often changing in wheeled huts called bathing machines that were rolled into the water. These costumes covered nearly everything and became very heavy when wet, which made actual swimming difficult.

The fitted one-piece arrived in the early twentieth century. Australian swimmer Annette Kellerman is often said to have been arrested on Revere Beach, Massachusetts, in 1907 for wearing a fitted one-piece; historians debate whether the arrest happened as the story is told, but she did popularize suits that let women swim properly. Over the following decades swimsuits grew steadily smaller, and in 1946 the French engineer Louis Reard introduced the bikini.

Even then, the bikini took years to become common. Through the 1950s, many one-piece swimsuits still had a short skirt panel across the front, often called a modesty skirt, along with boned bodices and a lined brief. Those skirted suits are the direct ancestors of today's swim dresses, and their shape returns regularly in retro-inspired swimwear.

Modest swimwear as its own category grew from the 1990s onward, as swim fabrics improved and designers began making full-coverage suits for women who wanted to swim without giving up their standards of dress. The burkini, designed in Australia in the mid-2000s, became the best-known example. Today the category includes everything from fashion tankinis to technical sun-protective sets, and many people who wear it have no religious reason at all.

What This Means for You

Modest swimwear is any swimwear that covers more than a standard swimsuit, and it ranges from a tankini to a full burkini. Start by deciding which zones you want covered, then pick the styles that cover them: tankinis and swim dresses for the midriff and seat, swim shorts for the thighs, long sleeves and leggings for the arms and legs.

Then judge every option wet. A good modest suit stays opaque, keeps its skirt and neckline in place and lets you swim the way you want to. Fitted pieces swim best; looser pieces cover the shape of the body but add drag.

Choose lined, darker or printed fabric for opacity, chlorine-resistant fabric if you swim in pools often, and proper support if you need it. Rinse after every swim and dry flat in the shade, and a modest suit will last as long as any other.
