Dresses in the ’40s were often simpler than in the decades to come, though ornamentation helped to disguise many a plain or heirloom dress during wartime rationing. Post-war some women made their wedding dresses from parachute fabric.
Pre-war weddings were simple, often slapdash if the groom (or bride) was shipping out soon after. Post-war weddings came to have a greater scale and folks had more time and money for larger celebrations.
Wedding rings for men gained popularity during the ’40s as a point of connection for the groom since so many of them shipped out soon after the occasion.
