Questions shoppers ask

What is a 34B in EU size?

A UK/US 34B is a 75B in EU and Japanese sizing, a 90B in France and a 12B in Australia.

What is a 32DD in other countries?

32DD (UK) is a 70E in EU sizing, 85E in France and 10DD in Australia. In the US it is also sold as 32DD.

Is a DDD the same as an F?

On Wacoal's conversion a US DDD corresponds to a UK E and an EU F. US brands are inconsistent above DD, so check the brand's own chart.

What is the biggest difference between UK and US cup sizes?

UK cups double letters (DD, FF, GG, HH) while US cups repeat D (DD, DDD) and then skip ahead. From DD upward the letters stop matching, so a UK G is roughly a US I.
