Demi's Birthday Suit, or The Suit, was a trompe-l'œil body painting by Joanne Gair photographed by Annie Leibovitz that was featured on the cover of the Vanity Fair August 1992 issue to commemorate and exploit the success of Leibovitz's More Demi Moore cover photo of Demi Moore one year earlier. As an example of modern body painting artwork, it raised the profile of Gair in pop culture as an artist in that genre.

Body painting is a form of body art where artwork is painted directly onto the human skin. Unlike tattoos and other forms of body art, body painting is temporary, lasting several hours or sometimes up to a few weeks. Body painting that is limited to the face is known as face painting. Body painting is also referred to as "temporary tattoo". Large scale or full-body painting is more commonly referred to as body painting, while smaller or more detailed work can sometimes be referred to as temporary tattoos.
