World War I[edit]
Changes dress during World War I were dictated more by necessity than fashion. As more and more women were forced to work, they demanded clothes that were better suited to their new activities; these derived from the shirtwaists and tailored suits. Social events were postponed in favor of more pressing engagements and the need to mourn the increasing numbers of dead, visits to the wounded, and the general gravity of the time meant that darker colors and simpler cuts became the norm.[1] A new monochrome look emerged that was unfamiliar to young women in comfortable circumstances. Women dropped the cumbersome underskirts from their tunic-and-skirt ensembles, simplifying dress and shortening skirts in one step.[2] By 1915, the Gazette du Bon Ton was showing full skirts with hemlines at calf length. These were called the "war crinoline" by the fashion press, who promoted the style as "patriotic" and "practical".[3]
Furthermore, people were dressing less extravagantly due to funds being put toward the war effort. According to Eileen Collard, Coco Chanel took notice of this and introduced costume jewelry. She replaced expensive necklaces with glass or crystal beads. "Without grading them to size, she mixed pearls with other beads to fashion original jewelry to be worn with her designs" that were inspired by women joining the workforce.[4]
