World War II ushered in an era of sartorial austerity in Europe and the U.S. In Washington, the enactment of Law 85 by the War Production Board, a subsidiary of the Department of Defense, restricted the use of silk, cotton, nylon and wool. On April 8, 1942, WWD ran “Fashions for Victory,” a piece that noted the law’s implementation and called on designers and private citizens to follow its rules. These restricted designers and manufacturers not only in terms of fabric choice, for instance, swapping rayon for silk, but in other aspects of business, such as mandating economical approaches “in the use of samples,” and “packing by increasing the number of units per package.” Designers were also required to “standardize sizes, length, widths, and the like” to improve durability of clothes. As for wartime aesthetics, though the military silhouette had a boyish vibe, an important underpinning development was sparked by the war: Underwire bras—produced with an economical mix of rayon, nylon, wire and elastic—hit the market.
