1930's Swimwear FashionWhile the 1920s would proved to be a liberating decade for swimsuit designers, as they experienced with new fabrics and cuts to make swimsuits shorter, tighter, and flirtier,this prototype consisting of a short, dress-style skirt with a lower neckline and bare shoulders remained the same into the 1930's. Until the introduction of the bikini in 1946, this style of maillot would be further shortened and tightened to progressively reveal more and more skin.
