In the 1920′s, women’s clothing were going through a revolution and dresses were shorter than never. Flapper dresses, along with a cloche or wreath headpieces completed the bridal look of the 20′s. Cap veils were also very popular, made of silk tulle and geometric trimming lace (Egyptian inspired pattern was a fad in the 20′s).
A decade later, wedding dresses came back to their full length style, as many brides found short dresses unsuitable for Church services. Slinky fabric, bias cut and a slim silhouette were the main characteristics of wedding dresses from the 30′s. Detachable trains were common during the Depression, allowing the bride to wear her wedding dress again as an evening gown.
I found some gorgeous 1920′s and 1930′s vintage dresses (from The Frock):
