Bikinis: Women's Bikini Swimsuits, Sets & Separates

A bikini is a two-piece women's swimsuit made of a separate top and bottom, worn for swimming, tanning and beach or poolside style. It comes in many cuts and coverage levels, and can be bought as a matching set or built from mix-and-match separates.

Bikini tops include triangle, string, halter, bandeau, balconette and underwire styles. Bottoms range from full and high-waisted through brazilian, thong and g-string, plus minimal micro, tiny and extreme cuts. You choose the top shape and bottom coverage separately.

The modern bikini was introduced in 1946 by French engineer-turned-designer Louis Réard, who debuted it in Paris. A rival designer, Jacques Heim, released a similar two-piece around the same time, but Réard's smaller design and the "bikini" name are what stuck.

Louis Réard named it after Bikini Atoll, the Pacific site of nuclear tests that were in the news in 1946. He expected his daring design to cause an "explosive" reaction — so he borrowed the name that was everywhere at the time.

Think balance, not rules. Hourglass shapes suit almost anything; pear shapes add interest up top; apple shapes draw the eye up with high-waisted bottoms; rectangle shapes add curves with string tops and cheeky bottoms; inverted triangles add volume below. Most of all, choose what makes you feel confident.

The most flattering bikini is the one that fits properly and matches your comfort level — fit beats cut every time. That said, matching sets and high-waisted bottoms are widely flattering, and adjustable string styles let you fine-tune the fit to your shape.

Snug but never digging in. Straps and ties should lie flat without pressing into the skin, the top should stay put when you move, and bottoms should cover what you want without riding up. If a set fits on top but not the bottom, mix-and-match separates fix it.

"Swimsuit" is the umbrella term for any swimwear, including one-pieces. A bikini is specifically a two-piece swimsuit — a separate top and bottom. So every bikini is a swimsuit, but not every swimsuit is a bikini.

Yes — and it's one of the best reasons to shop separates. Buy a top and bottom in different sizes for a true fit, or pair a bold top with a more balanced bottom. Keep one color story or texture and the two pieces read as a designed set.

Look for support: halter tops (which tie behind the neck for lift) and balconette or underwire styles give the most security and shape for a fuller bust. Wider straps and adjustable ties also help you dial in the fit.

Triangle and bandeau tops are classic choices for a smaller bust, and details like ruffles or padding can add the look of volume. Smaller busts also have the most freedom to wear minimal and string styles.

It's a coverage ladder. High-waisted is the most coverage; brazilian is cheeky but balanced; thong has a minimal back; and g-string is the narrowest back of all.

The most minimal coverage comes from micro, tiny and extreme bikinis, often paired with thong or g-string bottoms. For the boldest styling overall, see the slutty bikini edit.

Always check the product's size chart, since swim sizing varies by brand and cut. Measure your bust, waist and hips and compare to the chart. If you're between sizes or a different size top and bottom, choose mix-and-match separates or adjustable tie styles.

Absolutely — a bikini suits any age. Confidence and fit matter far more than a number. Many women love a high-waisted set for its waist definition and coverage, but every cut is fair game. Wear what makes you feel great.

The edit spans classic neutrals (black, white, sand) through bold and seasonal colors and prints, across every cut from triangle and string to high-waisted and micro. Check each style for its full color range.

Rinse in cool water after every swim to remove salt, chlorine and sunscreen, hand wash gently, and lay flat to dry. Avoid the dryer, hot water and harsh detergents, which weaken elasticity and fade color. Let it fully dry before storing.
