Size guide
A close, comfortable fit gives the built-in support its best shape. Use your bust measurement as the best starting point.
How to measure
Measure around the fullest part of your bust while wearing a comfortable, unpadded bra. Keep the tape level and relaxed. If someone can help, ask them to check that it is not pulling tight at the back.
Between sizes?
Choose the larger size for a softer, easier fit. Choose the smaller size only if you prefer a close fit and are between measurements.
Still unsure?
Start with your usual top size, then use the exchange window if the fit is not right. We make exchanges easy.
