This bra is soft and smooth on the skin, and it doesn't have underwires or hooks for a comfortable, non-restrictive fit all day. The flattering plunge design is perfect to wear with lower cut or V-neck shirts, with thicker straps designed to look less like underwear even if they peek out. Made with organic cotton.
