Warner Company refers to one of the first American manufacturers of women's foundation garments, such as bra and corset located in Bridgeport, Connecticut, United States. Warner Com pany was founded and created by Dr. Lucien C. Warner with his brother, Dr. Ira De Ver Warner. In 1935, Warner's introduced bras with fitted cups, ranging from A equivalent to small to D equivalent to large size. Since then, other manufacturers quickly followed suit.
Until the 1930's, the bra was more or less "one size fits all".
