1920s evening dresses

Here are two evening dresses from the V&A. It's funny how garments are named differently in different eras. Museums tend to have ballgowns from the 19th and mid-20th centuries. They do not seem to have any ballgowns from the early 20th century. Rather, they have evening dresses. Anyway, the one on the left is probably a Worth gown from 1928 or 29. It has the handkerchief hem that became popular at the end of the decade. The one on the right is probably from 1923 or 24, the years when hems were creeping up to their highest levels.
