Did J.Crew Just Crack the Code to Comfortable Shaping Swimwear? I Tested It (With Photos)

The design equally proportions control everywhere in the suit, so you’re not just benefiting from, say, an isolated tummy panel. The suit is made from two silky-feeling layers of fabric that are knit together or "interlocked" for light but totally visible compression. The inner layer is made to stretch out and then snap back, so the suit doesn’t lose its shape. Mine hasn’t, in the three months I’ve worn it to the beach, a pool and a hot springs resort.

The soft feel and overall durability are thanks to the material, a luxe-feeling blend of 38 percent recycled polyamide, 36 percent recycled polyester, 18 percent elastane and 8 percent polyamide. The legs are cut medium-high, which I appreciate since I’m not going for a hiked-up look. And the magic trifecta of adjustable straps, a long-torso size and that control fabric all together let me run, body surf and swim through waves without getting a wedgie. The highest compliment I can give this suit (other than thanks for holding in my tummy) is the fact that it’s so comfortable, I’ve even worn it as a cute layer under a blazer and with jeans. And I wasn’t at all uncomfortable. Congrats J.Crew—now I’ll be a loyal customer for your one-piece suits, too.
