November 3, 2026: Two Handkerchiefs and a $1,500 Mistake

On November 3, 1914, Mary Phelps Jacob, a 23-year-old New York socialite known as Polly, received a United States patent for her Backless Brassiere.

The idea started years earlier, when she was 19. Her whalebone corset kept showing through a sheer gown before a debutante ball, so she and her maid stitched together a soft replacement from two silk handkerchiefs and pink ribbon. Friends wanted their own, a stranger offered her a dollar for one, and her patent described a garment so free of bones and structure that it could be worn even by women playing tennis.

The harder part was turning the patent into a business. After marrying Richard Peabody and moving to Boston, Polly started the Fashion Form Brassiere Company with two women sewing on Washington Street. They made a few hundred bras and won some department store orders, but the company had no scale, no sales network, and no known brand, and her husband pushed her to close it. The Warner Brothers Corset Company of Bridgeport, Connecticut, already had the factories, suppliers, and store relationships she lacked, and it bought the patent for $1,500.

Warner mass-produced the design as corsets fell out of fashion and World War I metal shortages pushed women toward lighter garments. The company later introduced cup sizing, and by most accounts it earned more than $15 million from the patent over the next 30 years. Polly went on to reinvent herself in Paris as Caresse Crosby, co-founding the Black Sun Press. The story shows how the value of an idea often depends less on who invents it than on who has the means to sell it at scale.
