Why not the everyday form
Standard forms have a flat back designed to rest in a bra pocket. In water — where there is no pocket, gravity behaves differently and fabric moves — a flat-backed form migrates. Chlorine and salt also age the surface finish faster than any shower ever will.
What actually works
- A swim form with a suction back. A concave back that grips the chest when wet. It stays put through laps and waves. Ours is the Swim Form — chlorine- and salt-resistant outer skin.
- Pocketed swimwear. A suit with an internal pocket in the cup holds any form securely, swim form or not. Most mastectomy swimwear brands build this in; it looks like any other costume from outside.
- Both together for open water and serious swimming — belt and braces.
After the water
Rinse the form in fresh, lukewarm water the same day — chlorine keeps eating until it is rinsed off. Pat dry, back in the tray. That is the entire maintenance cost of a swim day.
Practicalities nobody mentions
The changing room takes less thought than you fear: the form goes on at home under the swimsuit, or in a cubicle like anything else. Wet silicone is no heavier than a wet swimsuit. And sunbathing with the form off is completely fine — the tan lines are your own business.
Swim forms are the easiest cross-sell in the category: every mastectomy customer has a holiday in the next twelve months. Stock three sizes and mention it once — see the catalog.
