Early 1920s women's dresses from a catalogue. The transition has been made to the dropped waist, but you still see the long hairstyles and skirts. The flapper look hasn't hit yet.

Illustration of two girls in day dresses from a 1910 catalog in my collection. The one on the right is designed to look like it has a separate jacket, but it's part of the dress. The one on the left has a detachable "girdle" (sash).
