Plus-size swimwear: built like lingerie

The moment of truth for a swimsuit in larger sizes is when you step into the water: the fabric soaks up, relaxes, and the volume you have to wear suddenly increases. A swimsuit that fits perfectly when dry may come loose in three seconds. It's this test, not trying it on in the changing room, that distinguishes well-constructed models from those that are merely stretchy.

What style for a larger size swimsuit

The larger size tankini often offers the best compromise: it covers the belly without the hassle of a one-piece when it comes to getting dressed again. The one-piece with cut-outs provides the most stable support for swimming, thanks to its continuous lining. The mix-and-match two-piece that you can select size by size remains the only solution to the common mismatch between bust and hip measurements, which is more pronounced in larger sizes.

What keeps a larger size swimsuit in place once wet

Three points need to be checked when dry and become critical in the water. The underwire first, which defines the cup when the fabric relaxes. The back next, which should fasten with hooks and not just a simple knot, as knots tend to come loose at the first dive. Finally, the straps should be wide and adjustable, anchored fairly wide apart. A larger size swimsuit sold in sizes S, M, L rarely meets all these conditions.
