When she appeared in the ball in a flowing evening dress, her natural breasts immediately attracted envious eyes. She then made many of the same productions for her girlfriends, and in 1914 she applied for a patent in the name of Caresse Crosby, the so-called "Backless Brassiere" was born at that time. . Later, the patent was bought by Warner Brothers Corset Company for $1,500. It has been estimated that the subsequent value of this patent must be at least four zeros after the 1,500$.underwear!
