The best bra is one that feels barely there, one comfortable enough to sleep in, sleek enough to work in, wicking enough to sweat in. For A and B cup gals, the Barely Bra is just that: light support, smooth and silky seamless construction, racerback. Molded cups keep the twins separate. Removable modesty. Poly/nylon/spandex. S(32BC-34AB), M(34BC-36AB), L(36BC-38AB), XL(38BC-40AB).
