The right size changes everything. Measure in two minutes, match your numbers to our charts, or let the Fit Finder do it for you.
All you need is a soft measuring tape and a non-padded bra. Measure in centimetres for the most accurate match.
Wrap the tape snugly around your ribcage, directly under your bust. Keep it level and breathe normally. This is your band measurement.
Measure around the fullest part of your bust, tape parallel to the floor and not too tight. This is your bust measurement.
Subtract your band from your bust. The difference in centimetres gives your cup size using the chart below.
