Sexy bra is designed for support with sheer touches all the way around. Made of polyamide and spandex. Multipart underwire cup is unlined (unpadded), sturdy, supportive mesh at the bottom and a lined side support sling for forward projection and lift. Stretch, striped, sheer mesh upper cup has a low profile edge. Angled and vertical cup seaming shapes breasts, with an opaque lower cup. Sewn-on, soft elastic at base of cups keeps fit close to the body. Center - wide, arched panel has decorative satin lacing. Flexible boning at side seams increases support and allows you to move comfortably. Sides and back are fine dual layer mesh with satiny stripe pattern outside and sewn-on elastic at top and bottom. Wide-set elastic straps with highly restricted stretch have a satin finish on exterior, soft backing, and fully adjustable coated metal hardware at back. Attached tags inside back carry fabric info. Hook-and-eye closure brings sides together at back with coated metal hardware. See Fitter's Comments below for hook counts.
