Lightweight and breathable: Ladies' strapless bra is made of 95% polyester fiber and 5% spandex. It is breathable, lightweight and fits gently to the skin. Easy to put on or take off. Support and push-ups: The strapless silicone bra helps to lift the chest and keep the chest in a good position to prevent sagging. The drawstring closure design makes your breasts look fuller and more cleavage. Invisible and skin-friendly: 100% pure medical silicone material, comfortable adhesive, will not leave marks on the skin after removing the bra. Completely invisible, very suitable for evening/party dresses, wedding dresses, and low-cut outfits. Be careful with repeated use: Sweat and high temperature may affect the viscosity of silicone.
