Nipple covers” (sometimes called “nipple pasties” or “nipple shields/petals” depending on design) are pieces made to cover the nipple/areola so that nipples don’t show through clothing — useful with backless dresses, thin tops, workout clothes, or any outfit where you don’t want to wear a regular bra.
When made of silicone, they generally use “medical-grade” silicone. That material is nontoxic, hypoallergenic, breathable, water- and sweat-resistant, and safe for skin contact.
Many silicone nipple covers are reusable — you clean them gently after use, let them dry, store them properly, and they can be worn multiple times.
Why people use them — benefits
Invisible under clothes: Silicone covers give a smooth, no-show look under tight, thin or sheer fabrics, backless outfits, and dresses where a bra would show.
Comfort & flexibility: Without straps, underwires, or bulky cups, they can feel much lighter — and silicone often feels close to natural skin, moving with your body.
Reusable and cost-effective: Instead of buying many bras for different outfits, a good pair of silicone covers can save money over time.
Skin-friendly (when quality is good): Medical-grade silicone minimizes risk of allergic reaction or irritation, making it suitable even if you have sensitive skin.
