the.com/fan dance

means A striptease performance in which the dancer uses large ostrich-feather fans to alternately conceal and reveal her body, turning the act of covering up into the real show.

from The form was popularized in the 1930s by American performer Sally Rand, who revived an older vaudeville idea of fan-veiling and made it a sensation at the 1933 Chicago World's Fair. The 'fan' is simply the literal feathered prop; the dance's artistry lay in the illusion of nudity managed entirely through timing and drafts of air, which let performers skirt indecency laws of the era while suggesting everything.
