Nipple covers or pasties are patches that cover a person's nipples and areolae which are affixed with adhesive. Pasties come in a variety of colors, diameters, and shapes. Though pasties come in a variety of sizes, they usually are not much larger than the areola.

Though pasties are commonly associated with burlesque and erotic entertainment, they are also at times worn more casually as an undergarment and occasionally as beachwear.
