This soft microfiber underwire bra features floral embroidered mesh along top of cups with exceptional support and non-stretch straps that won't slip. Made of polyester/nylon/spandex/rayon. Style # 2401 Multi-part underwire cups have fine mesh lining with seams to lift and round your bust. Horizontal cup seams give a slightly conical shape, while vertical seaming shapes and supports. Lightly padded support sling inside cup goes runs from side to side for additional support that positions you forward. Sewn-on elastic band along bottom of front keeps fit close. Center - tall, wide with arched underside for high tummy comfort, and bow at top. Flexible boning gives you more support at sides. Tall, supportive mesh sides and back feature sewn-on elastic at top and bottom for custom fit. Straps are soft, wide bands of non-stretch fabric that adjust at back with coated metal hardware. Back coated metal hook-and-eye closure, see Fitter's Comments below for hook count. Please Note: Elila has unique bra sizing. We recommend adding 3-4" to your rib cage measurement. So if you measure 33", you would start with a 36 band size. For band sizes 36 and up, you should go up a band size and down 2 cup sizes. (e.g. 36I(D6) would try a 38G(D4)).
