Mastectomy swimsuit size guide
Our main suggestion: choose the same size as your regular clothing size.
How to measure
Use a soft tape and measure over light underwear, or over the breast form you'll swim in.
- Bust: around the fullest part, keeping the tape level under the arms.
- Waist: around your natural waist, the narrowest point.
- Hips: around the fullest part of your hips and seat.

Garment measurements, taken with the shirt laid flat (double the chest width for the all-round measurement). Allow ±1–2 cm. The shirt is cut loose, so choose by how roomy you like it.
Your breast form and the pocket
The pocket holds the form. It doesn't change your swimsuit size, so choose your regular clothing size.
