What is a swim dress? It’s like a bathing suit only longer, perhaps to your knees. You can wear it on land as a dress or in the water. It is breathable and stretchy and fits very snugly so won’t ride up but you can wear a bikini bottom (not included) if you want. Made of Nylon/Spandex XTRA-LIFE LYCRA®. Ultra-resilient fabric snaps back like a pro and lasts 5-10x longer. Built-in PowerMesh shelf bra for throw-on-and-go support, removable cups. Racerback gives you freedom to move 16” under bust 19.5” across hips Body length in size medium: 36.5"
