Whoever came up with this suit was indeed a clever girl. If you haven't discovered the halter top already, discover it now. It's not just for teenagers. It's for anyone who wants a perfect, dialed-in fit up top, someone who wants to decide how much or how little support. Top is reversible. The bottom? Let's just say the clever girl who designed it knows a thing or two about how swim bottoms should look and fit on women's bottoms. Fully lined. 80% nylon, 20% spandex. Top: S(34ABC), M(36ABC), L(38ABC), XL(40ABC); Bottom: S(6), M(8-10), L(12), XL(14)
