In some localities strippers are required to obtain permits to work in adult entertainment. During a bikini performance, both breasts and genital areas typically remain covered by revealing attire, while dancers provide services and entertainment. Go-go dancers will retain their tops and bottoms for the duration of their performance. A female stripper whose upper body is exposed, but whose genital areas remain obscured during a performance, is said to be topless. Strippers who uncover the genital areas along with other clothing during a performance are said to be dancing fully nude. The fully nude practice is banned in many jurisdictions, but many dancers work around these constraints by selective uncovering of the vulva, anus, or both, for short periods of time, followed by immediate replacement of the clothing. Not all strippers are comfortable dancing topless or fully nude.
