Why do UK bra cups use double letters after D?

British sizing keeps every half-step in the alphabet, so DD, FF, GG, and HH all exist. US charts collapse some of those steps into single letters like G or H, which is why you slide one letter back when converting.

How can I tell if a bra already follows UK sizing?

Check the brand's origin and look for extra columns on the size label. If the tag highlights UK or UK/USA sizing separately, trust the UK column. Brands manufactured in the UK almost always use the British scale worldwide.

Does converting the cup change the band fit?

No. Band numbers represent the same body measurement in inches across US and UK systems. Only adjust the band when you intentionally want a tighter or looser fit, then offset with the appropriate sister size cup.

What if my converted UK size is hard to find in stock?

Search retailers that specialize in UK full-bust brands, or try the nearest sister size. For example, if 34FF is unavailable, test 32G or 36F to preserve cup volume.
