Waistlines started out high and by 1915 were below the natural waist. By 1920, waistlines were at hip-level. Between 1910 and 1920 necklines were lower and dresses could be short-sleeved or sleeveless. Women who worked during World War I preferred shorter dresses, which eventually became the dominant style overall. In addition to the shorter dresses, waistlines were looser and the dominant colors were black, white and gray.
By 1920, the "new woman" was a trend that saw lighter fabrics and dresses that were easier to put on. Younger women were also setting the trends that older women started to follow. The dresses of the 1920s could be pulled over the head, were short and straight. It was acceptable to wear sleeveless dresses during the day. Flapper dresses were popular until the end of the decade.
