HauteFlair Review: How the Sizing Actually Runs, Brand by Brand

HauteFlairUpdated August 202611 min readSizing & Fit

Straight Answer

Does HauteFlair run true to size?

There is no single answer, and any HauteFlair review claiming one is wrong. The catalogue carries three different sizing systems, and a size that fits in one will not necessarily fit in another. Panache uses UK band-and-cup sizing, running 28 to 46 bands in D through K cups. Dominique uses US band-and-cup sizing, reaching a 50 band. And designer houses including Cosabella, Hanky Panky, Bracli and Oh La La Cheri use alpha sizing, XS to XL. Those are not variations on one scale; they are separate systems that happen to share letters. The single most consequential thing to know: UK and US cup letters diverge after D and the gap widens, so a US DDD is roughly a UK E, and a UK G sits well above a US G. Order a UK G expecting US sizing and it will be far too large. That one confusion causes more returns than every quality issue combined, which is why this page exists.

The garment was made correctly. It was simply the wrong size, and often for a reason nobody explained at the point of ordering.

Three Systems UK vs US Cups How Each Brand Runs Measuring Fit Checks Between Sizes FAQ

The Short Version

Three sizing systems in one catalogue. Check the individual product chart.
UK and US cups diverge after D. US DDD is roughly a UK E.
Panache is UK sizing, 28 to 46 bands, D to K cups.
Dominique is US sizing, bands to 50.
Designer labels are XS to XL, sized to your widest measurement.
Band riding up means the band is too big, not too small.
Re-measure every 6 to 12 months. Size is not a fixed attribute.

3sizing systems in one catalogue, which is the root of most confusion.

DDD = Eroughly, converting US to UK. The gap widens above that.

80%of bust weight is carried by the band, which is why band fit comes first.

Three Systems, One Catalogue

This is the thing worth understanding before you order anything, and it is not obvious from browsing. The brands here do not use one sizing scale with slight variations. They use three genuinely different systems.

What Each System Is

System one · UK band and cupPanacheBands 28 to 46, cups running D, DD, E, F, FF, G, GG, H, HH, J, JJ, K. The doubled letters between single ones are what make UK sizing finer-grained than US, and they are also why the two systems drift apart. Construction assumes a full bust: seamed cups, side support panels, firm bands and tall wings.

System two · US band and cupDominiqueBands up to 50, cups running A, B, C, D, DD, DDD then continuing into F, G, H, I depending on style. Covers the larger-band end of the range, with full-figure styles concentrated from DD upward. Four-row closures and tall wings are standard, which is what makes a larger band work rather than roll.

System three · alphaCosabella, Hanky Panky, Bracli, Oh La La CheriXS to XL, or plus equivalents. These houses cut in stretch lace with a wide fit range, which is why one alpha size can cover what would be two or three bra sizes. The trade is precision: forgiving where you are between sizes, imprecise where you need a specific cup volume held in a specific place.

The practical upshot is simple. Work out which system you are looking at before you look at the size. The product page tells you: if the options are Band Size and Cup Size, you are in a band-and-cup brand; if it is a single Size dropdown reading S, M, L, you are in alpha sizing.

UK Versus US Cups: The Expensive Confusion

The two systems agree up to a D and then separate, because UK sizing inserts a doubled letter between each single letter and US sizing does not. By the time you reach the middle of the alphabet they are describing very different volumes.

US cup	Approximate UK equivalent
D	D
DD	DD
DDD / E	E
F	F
G	FF
H	G
I	GG
J	H

Read that table in the other direction and the risk becomes obvious. A UK G is roughly a US H, so someone who wears a US G and orders a UK G has ordered a cup larger than they need. The error compounds as the letters climb.

Conversions are approximate, not exact

Treat any conversion table, including this one, as a starting point rather than a guarantee. Brands differ in how they draft a given size, and cup shape matters as much as cup volume. If you are converting between systems for the first time, that is exactly the situation worth asking about before ordering. Our size charts guide explains why nothing in this category converts cleanly.

Measuring Properly

Step 1

Ribcage, Directly Under the Bust

Snug and level all the way round, taken in a non-padded bra or without one. Round to the nearest even number. That is your band. Add nothing to it, whatever older guidance may have told you.

Step 2

Bust, at the Fullest Point

Level all the way round and not pulled tight, since compressing the tape produces a smaller cup than you need. Standing upright rather than leaning forward.

Step 3

Subtract, Then Count Letters

Subtract the band from the bust. Each inch of difference is one cup letter: one inch an A, two a B, three a C, and so on. Then apply that to whichever system the product uses, which is where most errors happen rather than in the measuring.

Step 4

Check the Product Chart Anyway

Your measured size is a starting point, not a verdict. Brands draft differently, and the chart on the individual product reflects that garment rather than a site-wide average. Two minutes of checking saves a return.

Five Checks When It Arrives

These apply regardless of brand or system, and four of the five are about the band, because the band is doing roughly eighty percent of the work.

What to Check Before Removing Tags

OneIs the Band Level?It should sit parallel to the floor all the way round, not riding up at the back. A band riding up is too large for the load it is carrying, which is the opposite of what most people conclude. Go down a band and up a cup to keep the same volume.

TwoDoes It Fasten on the Loosest Hook?When new, yes. The tighter hooks are the adjustment you will need in six months as elastic relaxes. A bra that only fits on the tightest hook on day one has nowhere to go.

ThreeDoes the Gore Lie Flat?On a wired bra the centre panel between the cups should touch your sternum. A visible gap means tissue is occupying the space the gore needs, which means the cup is too small. This single observation resolves more fit problems than any measurement.

FourScoop, Then Look at the EdgesLean forward and settle each breast fully into the cup, then check the top edge and underarm. Spilling means too small; gaping means too large or the wrong cup shape. Both on the same bra usually means a shape mismatch rather than a volume one.

FiveSlip the Straps OffA correctly fitted bra holds almost everything without them. If the bust drops noticeably, the band is not doing its job and the straps have been compensating, which is why your shoulders hurt by evening.

If You Are Between Sizes

Ordering two sizes and returning one works, and asking first works better, because brand-specific fit knowledge is precisely what a size chart cannot give you.

Email help@hauteflair.com with your measurements and the style you are considering. Whether a particular Panache cup runs shallow, whether a Dominique band is firm for its size, whether an alpha piece has enough stretch to cover two sizes: those are answerable questions and the answers are not on the product page.

Two general rules while you wait for a reply. Sister sizing is the correct adjustment when the band is wrong, since going down a band and up a cup holds volume constant while tightening the band. And in alpha sizing, size to whichever of bust or hip falls higher on the chart, because a straight-cut garment must clear your widest point.

Almost every bra someone tells us is badly made turns out to be well made in the wrong size. The two feel identical when you are wearing them.

What This Means for You

There is no site-wide answer to whether HauteFlair runs true to size, because three sizing systems sit in one catalogue. Panache is UK band-and-cup, Dominique and the everyday brands are US band-and-cup, and the designer labels are alpha.

So check which system a product uses before you check the size. If you are converting between UK and US cups, remember they diverge after D and the gap widens, so a UK G is roughly a US H rather than the same thing.

Then measure properly, check the individual product chart rather than a site-wide range, and judge the band first when it arrives. And if you are between sizes, ask before ordering rather than after.

Frequently Asked Questions

Does HauteFlair run true to size?

There is no single answer, because the catalogue carries brands using three different sizing systems. Panache uses UK band-and-cup sizing, Dominique uses US band-and-cup, and designer labels such as Cosabella and Hanky Panky use S to XL. A size that fits in one will not necessarily fit in another, so check the chart on the individual product rather than assuming a site-wide answer.

What is the difference between UK and US cup sizing?

They diverge after D and the gap widens. UK sizing runs D, DD, E, F, FF, G, GG, H, HH, J, JJ, K, adding a doubled letter between each single one. US sizing runs D, DD, DDD, then G, H, I. A US DDD is broadly a UK E, so a UK G sits well above a US G. Always check which system a brand uses before ordering.

How do I measure for a bra?

Measure your ribcage directly under the bust, snug and level, and round to the nearest even number for the band. Then measure the fullest part of the bust, level and not pulled tight, and subtract the first from the second. Each inch of difference is one cup letter. Measure in a non-padded bra or without one.

Why does my bra size change between brands?

Cup shape and depth vary even at the same nominal volume, band elasticity differs, and wire width differs. A brand cutting for a projected breast shape fits differently from one cutting for a shallower shape at the same labelled size. Bra sizing is more consistent than dress sizing but is not interchangeable.

What is sister sizing?

Sister sizes hold the same cup volume on a different band. Going down one band and up one cup, or the reverse, keeps volume constant while changing band tension. A 38D, 36DD and 40C hold roughly the same amount. It is the correct adjustment when the band is wrong, rather than changing the cup alone.

Should I size up or down in alpha-sized lingerie?

Size to whichever of your bust or hip measurement falls higher on the chart, since a straight-cut garment must clear your widest point. Where they sit in different size bands, going up gives the skimming fit these pieces are cut for. Sizing to the smaller measurement produces clinging at the other end.

How does Panache sizing run?

Panache uses UK band-and-cup sizing across 28 to 46 bands and D to K cups. It is a full-bust brand, so the construction assumes a larger cup: seamed cups, side support panels and firm bands. If you are new to UK sizing, convert carefully, since the letters do not map onto US sizing after D.

How does Dominique sizing run?

Dominique uses US band-and-cup sizing and covers the larger-band end of the range, reaching a 50 band, with full-figure styles concentrated in DD through I. Construction includes seamed cups, tall wings and four-row closures, which is what makes larger bands work rather than simply scaling a smaller pattern.

What size should I order in Cosabella or Hanky Panky?

These houses manufacture in alpha sizing rather than band and cup, so use the brand's own chart against your measurements rather than translating from a bra size. Many of their pieces are cut in stretch lace with a wide fit range, which is why one size often covers what would be two or three bra sizes.

How do I know if a bra fits correctly?

The band should sit level all the way round and fasten on the loosest hook when new. The centre gore should lie flat against the sternum. Cups should contain all tissue without gaping or spilling after scooping. Straps should carry only a minority of the weight. A band riding up means the band is too large, not too small.

What if I am between sizes?

Email help@hauteflair.com with your measurements and the style you are considering before ordering. That is faster than ordering two sizes and returning one, and brand-specific fit knowledge is exactly the thing a size chart cannot give you.

Does swimwear size the same as lingerie?

Not reliably. Some swim is sold in band and cup, most in alpha sizing, and swim fabric behaves differently when wet, gaining some length and losing some tension. Check the individual chart, and where a swim top has a structured cup treat it as you would a bra.

How often should I re-measure?

Every six to twelve months, and after any significant change in weight, pregnancy, or medication that affects fluid retention. Bra size is not a fixed attribute, which is why a size that fitted two years ago may not now.
