Imagine living in a world where fabric was scarce, rationed and silk went for making parachutes. War brides (usually quick to marry fiances going off to war) sometimes had to make do with a best dress or a suit to tie the knot. Formal to-the-floor gowns were offered in the synthetic fabrics that were the newest thing. The classic silhouette of this era was an A-line with a V-neck and long sleeves usually in a high sheen satin.
Above: Shorter veils sporting poufs and wraps of netting and flowers were trendy for the more informal or secular wedding.
Below: The Silhouettes below are A-line in the highest-sheen white satin. The dresses directly below sport peplums, graduated apron-like over skirts characteristic of the 40s. Another clue to recognizing fashion from this era is padded shoulders. In the images below, Ginger Rogers and Martha Scott are flaunting big shoulders with hats holding their veils.
