Wikipedia: Mae West
Mary Jane “Mae” West (August 17, 1893 – November 22, 1980) was an American actress, singer, playwright, screenwriter, comedian, and sex symbol whose entertainment career spanned seven decades. She was known for her lighthearted, bawdy double entendres and breezy sexual independence. She was active in vaudeville and on the stage in New York City before moving to Hollywood to become a comedian, actress, and writer in the motion picture industry, as well as appearing on radio and television. The American Film Institute named her 15th among the greatest female stars of classic American cinema.

In popular culture
During World War II, Allied aircrews called their yellow inflatable, vest-like life preserver jackets “Mae Wests” partly from rhyming slang for “breasts” and “life vests” and partly because of the resemblance to her torso. A “Mae West” is also a type of round parachute malfunction (partial inversion) which contorts the shape of the canopy into the appearance of an extraordinarily large brassiere.
