As its name implies, this bra top works double-time as an everyday bra or for yoga - on its own or under a tee or tank. The organic cotton/spandex blend fabric provides soft, comfortable support. The wide fabric band doesn't bind or dig in. You'll hardly know you're wearing it! Our bras are great for every day, sleep, nursing, travel and gentle workouts. Made in the USA. Sizing - Small: 30-32, A-B. Medium: 32-34, B-C. Large: 38-40, D-DD.
