"It is that quality possessed by some, which draws all others with its magnetic force. With It you win all men if you are a woman--and all women if you are a man. It can be a quality of the mind as well as a physical attraction. It is self-confidence and indifference as to whether you are pleasing or not, and something in you that gives you the impression that you are not at all cold. That's It."

- Elinor Glyn, describing Clara Bow, quoted in Nylon magazine.
