Founded by Lauren Yerkes — twenty years in fashion, the last as Chief Merchandising Officer at REVOLVE, and a breast cancer survivor who couldn't find a swimsuit she wanted to wear after her double mastectomy. So she made one. Every POST SWIM suit is designed for scar coverage, prosthesis pockets, and asymmetry — then cut and sewn in Los Angeles, and named after someone she loves.
A mastectomy or lumpectomy shouldn't mean giving up the swimsuits you love. Our mastectomy swimsuits are built for women in every stage of the journey: pre-surgery, mid-recovery, post-reconstruction, or years down the road. Mastectomy swimsuits designed specifically for life after mastectomy: soft, flexible construction that won't dig into healing skin, built-in prosthesis pockets for symmetry and support, and necklines, seams, and straps placed to avoid irritating scars, drains, or port-a-cath sites.
Whether you're flat on one or both sides, reconstructed, or somewhere in between, you'll find tops, one-pieces, and rashguards built around real post-mastectomy and post-lumpectomy bodies, not around them. Many styles are also flat-friendly, meaning they're cut to lay smoothly against the chest without padding or shaping that assumes reconstruction — check each product page to see which.
Explore flat-friendly swimsuits, prosthesis-friendly swimsuits, and chest coverage styles to find the exact fit for where you are today, that might look different from where you are tomorrow.
Designed by someone who needed it
I spent twenty years in fashion, the last of them as Chief Merchandising Officer at REVOLVE, deciding what women would want to wear next.
Then, at 37, I was diagnosed with stage 2 triple-negative breast cancer. A double mastectomy, reconstruction, seven months of treatment and a feeding tube. On November 11, 2022, I was declared cancer-free. The next summer, we planned a trip to Maui.
I couldn't find a swimsuit.
Not because nothing existed. Because everything that existed had been built by people solving a medical problem, and nothing had been built by someone who cared how it looked. The suits with pockets were designed to be prescribed, not chosen. The pretty ones weren't cut for a body like mine. I was being asked to pick between feeling covered and feeling like myself, and I'd spent an entire career proving women shouldn't have to pick.
So I made the suit I wanted.
That's POST SWIM. Longer bands and higher backs, so a scar sits under the fabric instead of above it. Wider straps that cover a port scar. Soft cups and stretchable pockets that hold a prosthesis without announcing it. Removable padding for asymmetry, adjustable straps, clasp closures for the days your arms don't move the way they used to. We developed the fit with two board-certified surgeons, Dr. Lisa Guerra and Dr. Wendy Ng, so the details are right.
But that's the second thing you should notice. The first should be that you like it.
Every suit is cut and sewn in Los Angeles, and every one is named after someone I love. Coverage is a choice here, how much, where, and on which day. Some women wear these because of surgery. Plenty wear them because they're good swimsuits.
Both are the point.

FAQs
Yes — several styles in this collection include a bra shelf with a pocket built to hold a prosthesis securely in place, so you're not adjusting or double-checking throughout the day. If you're shopping for a specific style, check the product description for a "prosthesis-friendly" note — a few pieces are built more for flat or au natural bodies and aren't designed for a form.
Our flat-friendly styles are built with no molded cups, so there's nothing to gape, dig, or pull away from your chest. Instead of forcing a shape, the fabric and support are designed to sit close and stay put, whatever your chest looks like right now.
Many of our necklines and bands sit higher and wider than a standard swimsuit specifically to offer more coverage around scars, ports, and healing skin. Check out the Lauren One Piece and the Melanie Rashguard.
Mastectomy styles are built to support prosthesis wearers, reconstruction, and implants, often with a bra shelf or pocket. Most flat-friendly styles skip the built-in cup entirely for a smooth, comfortable fit with nothing to shift or gape. Many women mix and match based on how they feel day to day.
Completely normal to feel unsure here, especially if your size has shifted since surgery. Start with our size chart and go with your current measurements over what you used to wear. Reference each product for details on true sizing recommendations.
