Pasties (singular pasty or pastie) are patches that cover a person's nipples and areolae, typically self-adhesive or affixed with adhesive. They originated as part of burlesque shows, providing a commercial form of bare-breasted entertainment. They are also worn as an undergarment in lieu of a bra, or visibly as a fashion accessory, and are sometimes called nipple stickers. Pasties are also, at times, used while sunbathing, worn by strippers and exotic dancers, or as a form of protest during women's rights events such as Go Topless Day. In some cases this is to avoid potential prosecution under indecency laws. Pasties are sometimes worn by bikini baristas, staff hired to serve coffee from roadside huts while wearing lingerie, thongs, or skimpy swimwear. Design Pasties come in a variety of colors, shapes, and sizes. They can be made from a variety of materials, including craft foam, artificial leather, buckram and plastic. Some are skin-colored while others are produced with decorative designs on them. They are often smaller in countries such as Japan than they are in America as they are typically not much larger than the areola. No straps are used to hold pasties in place, so they require a tape or glue fixative. This is often gum arabic, although other types of glue are sometimes used including liquid latex and eyelash extension glue. Nevertheless, they can fall off as a result of sweating or movement. The burlesque dancer Candy Cotton reported that a pastie she was wearing flew off into the audience during her act. Pasties are typically designed to be left on for hours rather than days. Removing them can be painful, particularly if they have been left on for too long. Adhesive removers are sometimes used to help remove them, though these are not usually designed for human skin. The adhesive used to attach pasties cause problems for people with sensitive skin. The burlesque dancer Lili St. Cyr found that her nipples often hurt when she removed her pasties at the end of the night, and in consequence she watered down the glue that she used. To reduce the chances of an allergic reaction, modern pasties are mostly attached with glue designed for cosmetic use or are held in place using double-sided fashion tape. People with sensitive skin often prefer hypoallergenic nipple covers. The most popular and common type are made from the hypoallergenic polymer silicone, rather than materials
