Bras 75B

How to find your size

Sister sizes for 75B: 70C, 80A. If 75B holds well around the band but the cup digs in or gapes, reach for a sister size instead of changing only the letter — cup volume stays similar while the band changes.

At this cup size, padded and push-up models work well because they add volume, as do smooth cups under fitted clothes.

Size 75B is described by two numbers: a band measured under the bust in the 73-77 cm range and 13-15 cm by which the bust measurement exceeds it. In practice it is one of the more frequently chosen sizes, so the choice of styles here is wide - from smooth moulded cups to lace.

The biggest mistake at this size is reaching for a bigger band for comfort. The band, not the straps, is what provides support, and it should sit horizontally along its whole length. Fasten a new bra on the loosest row of hooks - leave the tighter ones for later, once the elastic has stretched.

The sister sizes for 75B are 70C on a narrower band and 80A on a wider one. The cup volume in these is similar and it is the band that changes, so if your back feels tight while the cup sits well, try the version with the wider band.

Which style to choose

At a B cup, padded and push-up models come out well, because they give shape without flattening, as do wire-free constructions for wearing at home. Check that the top edge of the cup does not gape - that is a sign the model is too big or has too strongly contoured a top.
