The charts below show how brands from different countries label their bras. There is significant variation between brands, especially above a D cup, so this is only general guidance. For advice on getting the right fit, please go to our bra fitting tips.

Briefs sizing often follows dress sizing – 8, 10, 12, etc. Some brands, however, use a different system, sizing their briefs as 1, 2, 3, 4 and 5. Where this is the case, we give the equivalent dress size on the product page. Many briefs are also available in small, medium and large – again, the equivalent dress size is given on the product page.
