How to measure
To help decide which size will fit you best, we recommend taking the following measurements. For the best results, measure wearing underwear only.
Measure under your arms around the fullest part of your chest, running the tape under your arms. Make sure the tape is firm but not tight, and that it lies flat across the back.
Measure around your natural waistline, keeping the tape comfortably loose.
All our underwear is a firm fit. We recommend that you take the next size up if you like extra room.
