In 2500 BC, Greek woman on the isle of Crete started wearing a garment resembling a bra pushing their bare breasts up and out of their clothing. Then Roman woman squeezed their breasts into a breast band to minimize their busts and Egyptian women painted their breasts.
In 1913 Mary Phelps Jacob came up with the idea of a bra-like garment to wear under a gown that was sheer. Taking two hankies, ribbon, and cord she devised a bra. And women started ordering these Sexy lingerie from her. In 1914 she patented her idea and it was titled “‘Backless Brassiere’. Jacob later sold her company to Warners Brothers Corset Company for $1,500.
Before Jacob had her brilliant idea women had been wearing binding corsets or the union suit which was woolen and warm but not supporting or flattering.
