how did people dress in 1915
Girl's Clothes. In 1915, girls primarily wore dresses or skirts that ended at about the knee, paired with knee or ankle socks. Dress yokes dropped to the thigh. Girls commonly wore middy blouses -- shirts with a sailor-style collar and loose waist -- and skirts to school.
Boys in 1915 wore mostly short pants paired with white or light-colored, button-down shirts and sometimes jackets matched to the pants. Suspenders, not belts, held up short pants.
