History of Brassieres
Derived from the French word meaning upper arm, the brassiere is a mass-produced support undergarment worn by women that consists of two fabric cups attached to two side panels, a back panel, and shoulder straps (unless strapless) that fits snugly. They are sized according to a universal grading system first introduced by Ida Rosenthal, the founder of Maidenform, in 1928. Two measurements are crucial to determining brassiere size: the chest circumference and the fullest part of the breast.
