‘Mae West’ ? https://en.wikipedia.org/wiki/Mae_West

• During World War II, Allied aircrews called their yellow inflatable, vest-like life preserver jackets« Mae Wests » partly from rhyming slang for « breasts »^[120] and « life vest » 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.^[121]
