See the size chart below. If you are unsure between two sizes, we recommend choosing the larger one.
Use this guide to find your size. All measurements are body measurements, not garment measurements. Measure yourself with a soft tape measure over thin clothing and compare your numbers with the table below.
How to measure
Bust: measure around the fullest part of your chest.
