Our prosthesis-friendly swimwear is intentionally designed for women who wear a breast form after a mastectomy, with thoughtful features to help keep your prosthesis comfortably and securely in place. These styles are made to give you the coverage, support, and confidence you want so you can feel comfortable in a suit designed with you in mind.
Wearing a breast form or prosthesis shouldn't mean settling for swimwear that shifts, gaps, or feels like an afterthought. This collection is built specifically for prosthesis-friendly fit: secure, built-in pockets that hold a breast form or swim form in place, supportive construction that keeps everything symmetrical in and out of the water, and necklines and seams positioned to stay comfortable against healing skin or a mastectomy scar.
Whether you're wearing a silicone prosthesis, a lightweight swim form, or trying one for the first time, these styles are designed to move with you. Several pieces here also do double duty as flat-friendly or scar coverage swimwear, so if your needs shift between flat and prosthesis over time, you can find the right support without starting your search over.
We also carry the TruLife Active Flow Swim Form directly in this collection, a lightweight, chlorine-resistant swim prosthesis designed to move naturally in water, so you can shop the form and the swimsuit built to hold it in one place. Not sure what size to start with? Our size guide covers both suit sizing and the TruLife Active Flow form sizing in one place.
POST SWIM was founded by a breast cancer survivor who knows firsthand how much a well-fitting swimsuit changes how it feels after a mastectomy, which is why the brand builds for every path forward, including prosthesis-friendly fits, not just the one she chose herself.
Coverage is a choice, and prosthesis-friendly doesn't mean one specific look. You'll find bikini tops, one-pieces, and tankinis here, from minimal to maximum coverage. Explore mastectomy swimwear and flat-friendly swimsuits if you're still deciding what fits best, or shop by chest coverage to narrow in on your ideal level of support.
