1917In the third year of World War I, a woman's bathing suit consisted of a heavy wool chemise which was worn over bloomers. Shoes and stockings were taken off only by the very daring and unconventional!
1918Although skirts got a little shorter, beach outfits like this, according to a fashion magazine, were designed, "to defy wind, wave and the scrutiny of man". Water wings were also much in use by women.
