Strapless Bras are essential to every woman’s lingerie wardrobe, and many women prefer that this type of bra comes with underwires. Underwire bras have wires built into the underside of the cups that lift, separate, shape and support a woman’s breasts. The underwires, which are circular strips made of metal or plastic, fit inside the cloth along the bottom and sides of the bra cups. Many women swear by underwire bras and will not wear any other kind of bra. Although underwire bras are not considered as comfortable as wireless bras, the support they offer is viewed as superior.
