Reusable Silicone Nipple-less Covers with Breast Lifts are the perfect solution to ensure your nipples don't show and keep your breasts lifted and perky while going without a bra, are generally used as undergarments for swimwear, formal dresses, and revealing tops that may not provide enough back coverage for wearing a full bra. After each use, simply hand wash the silicone pasties with warm water and mild soap.
