Essentially though, these letters are all to do with proportion – that means, someone wearing 12D has significantly smaller breasts than someone in a 16D, even though they are both wearing a D bra.

One thing you need to know, band sizes stay the same in US and UK sizing, e.g., a US 32 band is the same as a UK 32 band.
