such as latex that can cause allergic reactions. The availability of suitable adhesives was a necessary precursor to their introduction, and their name derives from the word paste. Modern pasties are often self-adhesive. Some are for single-use, while others are washable and can be reused. Entertainment Early versions of the pastie were worn by belly dancers and exotic performers at the 1893 World's Fair. These consisted of small metal plates covering the front of the breasts, and were often decorated with gems or metallic details where the nipples would be. They were subsequently worn by some circus performers during their acts. The modern form of the pastie first appeared in burlesque and striptease in the 1920s as a way to avoid breaking the law by performing topless or nude. Pasties came to be regarded by some as more aesthetic and erotic as they developed into a way of drawing attention to the breasts and nipples. They were worn in cabarets such as the Folies Bergère and Le Lido. Burlesque performer Carrie Finnell is attributed with adding tassels which hang from the center and incorporating tassel twirling as part of a performance. Finnell and Sally Rand rose to prominence as burlesque performers in the 1920s and 1930s. At that time there was a shift away from pasties decorated with tassels or gems toward nipple-like pasties, making the appearance of nudity more realistic. From the early 1930s burlesque performers typically wore pasties and a G-string, undressing to these as the final reveal of a striptease. The burlesque performer Gypsy Rose Lee included pasties as part of her onstage outfit in the 1930s and 1940s, and made adjusting them part of her act. Dancers in US strip clubs continued to wear pasties in the 1950s and 1960s, with Carol Doda becoming the first fully topless public dancer in the country at the Condor Club in San Francisco in 1964. The use of pasties in burlesque and striptease declined during the subsequent decades, but they became fashionable again with the appearance of neo-burlesque in the 1990s and 2000s, worn by performers such as Jo Weldon and Dita Von Teese. The Suicide Girls, a troupe that started in 2001 as an homage to Bettie Page, included pasties in their live performances. Wearing pasties pays tribute to burlesque performers of the past, and it is also sometimes necessary to allow neo-burlesque dancers to perform in venues
