H Cup Bras

There is no single answer, because the cup is relative to the band. An H cup on a 28 band holds far less than one on a 44 band. In UK sizing the run is D, DD, E, F, FF, G, GG, H, making H a true full-bust cup; US sizing has fewer steps so a US H is smaller. Always read the letter with its band number.

An H cup bra is a full-bust bra where H describes the difference between your bust and underbust measurements. Because the cup grows with the band, a 30H and a 40H hold very different volumes. H cup bras are built for support, with firm bands, seamed or side-support cups, wider straps and usually four or more hooks.

No. UK sizing adds DD, FF and GG steps that US sizing does not, so a UK H sits further along the run and is a larger cup than a US H at the same band. Most H cup bras sold in the US are UK-sized because the brands making them are British, so assume UK unless the brand states otherwise.

Nine: 28H, 30H, 32H, 34H, 36H, 38H, 40H, 42H and 44H, each its own collection with live stock. 34H and 36H are the deepest at 42 styles each; 42H and 44H are the smallest at 19 and 18. 28H is a size most mainstream retailers do not make at all.

Sister sizes hold the same cup volume on a different band. If the cup fits but the band is loose or tight, size across: down a band means up a cup, and vice versa. A 36H holds the same volume as a 34HH and a 38G. At H cup this is the fastest fix for the most common fault.

A riding band means the band is too big, not that the cup is too small — and at H cup it is the single most common fitting error. Go down a band and up a cup: if you wear 38H, try 36HH. The cup volume is identical and the firmer band will sit level and carry the weight.

Measure your underbust snugly around the ribcage just beneath the bust, then measure around the fullest part of the bust without compressing. The difference gives your cup. If you fall between two bands, take the smaller one and go up a cup. Sizing varies by brand, so check each size chart before ordering.

A firm non-stretch band that does the support work, wire that fully encircles the breast and sits flat on the ribcage, three-part or side-support cups rather than moulded, wider fully adjustable straps, and four or more hooks. These are what make a full-bust bra comfortable through a whole day.

Yes, from Panache Sports and Dominique. At H cup look for encapsulation — separate cups holding each breast individually — combined with compression and a wide, firm band. Compression-only styles that work at smaller cups flatten rather than support and do not control movement during high-impact activity.

Yes, though the range is narrow at this size. A full-bust strapless needs a deep grippy band, silicone lining and usually light side boning, because the band alone carries all the support. Getting the band size exactly right matters more here than in any other style. Check the strapless edit for current H cup stock.

Moulded cups are formed from a single piece of foam, and above roughly a G cup that shape becomes too shallow to project and contain a full bust properly. Seamed three-part cups do the job better, which is why specialist brands build them that way. Our deeper moulded range sits at F and G.

We carry H cup from Panache, Panache Cleo, Panache Sculptresse, Panache Sports, Le Mystere and Dominique. These are the specialist full-bust houses that engineer support into every style, rather than mainstream labels that stop at DDD or G and treat larger cups as an afterthought.

Most mainstream retailers stop at DDD or G, because larger cups need different pattern-making, more panels and more expensive construction. That leaves H cup to a handful of specialist brands, which is why a curated full-bust collection is usually a better starting point than a general department store.

The band sits snug and level all the way round and carries most of the support. The wire encircles the breast and lies flat on the ribs. The centre gore touches the sternum. The cup edge is smooth with no spillage or wrinkling. The straps sit comfortably without digging. If any of those are off, try a sister size.
