Sizing Guide

Bra sizes can be very confusing, all these numbers and letters - but what do they actually mean?

There are 2 measurements that make up a bra size, the band size followed by the cup size. For example 32F: 32 is your band size, and F is your cup size. It is also good to note that different brands will have different sizing charts, so you may be slightly different sizes across various brands, but this is very normal and great to keep in mind when bra shopping.

Please see our size guides below if you need to convert your international bra size to a UK size. This is separated into band size and cup size.

The above size chart is based on generic bra sizes. Below we have put together a more detailed look at the sizing for different brands.

Size By Brand

PrimaDonna

PrimaDonna bra sizes skip a UK DD, which means if you are after this size we would recommend trying the D cup as the cup sizes come up slightly larger.

Ultimo

The band sizes for Ultimo are slightly tighter fitting than the usual bra band, therefore it may be ideal to go up in your usual back size, and go down in the cup size.

Elomi and Goddess

These Plus Size brands specifically cater to those with fuller figures and those who are blessed with larger busts.
