These small, circular or flower-shaped adhesive coverings are meant to cover only your nipples, so they’re a great option for low-cut tops and thin or sheer fabrics that might make your nipples visible. Stick the adhesive side onto your nipple and press it down gently. Look for a color close your skin tone for the least noticeable solution.  You can buy stick-on nipple covers online or in stores that sell bras and related accessories. Wash the covers with gentle soap and water after use and store them in their original packaging to reuse. The adhesive will wear out eventually, but many covers come with a 30 to 50-wear guarantee. Like the silicon nipple covers, pasties are placed directly over your nipple and stay on using a sticky adhesive. They’re cheaper and come in packs of 4-6, because they’re meant to be for one-time use. Some people prefer pasties because they’re less noticeable under tight shirts than silicon covers, which are thick and might stand out under a tight fabric. On the flip side, pasties might not be as adept at concealing your nipples when they harden. Try both nipple covers and pasties to see which works best at concealing your nipples. Cut the pad in half, then cut out 2 circles large enough to cover your nipples, keeping the paper covering the adhesive in place. Stick them on over your nipples and throw them away when you’re done.  Like pasties, this method might not conceal hard nipples well under a tight shirt. Try it at home before you wear it out. You can also use small bandages or surgical tape.
