Prosthesis Size Chart
This prosthesis is designed for use with pocketed mastectomy swimwear and is compatible with select POST SWIM styles. It is intended to sit securely and smoothly against the chest for a natural, supported silhouette.
We currently offer sizes 5–9, thoughtfully selected to support a wide range of band and cup sizes within our community. As POST SWIM continues to grow, expanding our size offering is something we care deeply about.
For best results, we recommend pairing with properly fitted pocketed swimwear to ensure secure placement and optimal comfort.

Description
The Boyshort is a high-waisted swim bottom with a wide waistband and clean finish, designed for confident coverage and a sleek, streamlined silhouette. Style it back to the Melanie Rashguard or Lolo Halter Top for a complete look.
Disclosure: This piece is a factory second due to minor manufacturing imperfections — here, the waistband elastic is an off shade. It's not noticeable when dry; when wet, the darker elastic may show slightly. There may be other small imperfections not pictured, but every piece is new and unworn. Final sale.
