Jade Swim Nova One-Piece in Nude, X-Small: Aside from the fact that it’s made of sustainable OekoTex-certified fabric, what we love about Nova is its sophisticated cut. Between the halter top in front, the half-moon cutout in back, and the slender straps connecting the two, it nails the chic-without-trying look. And how good is that earthy clove hue? 78% nylon, 22% spandex.
