My parents had my older half-sister in their wedding, she and mom had "mother-daughter" vows. My mother made her dress (it weighs fifteen lbs), my dad made his garb and my elder sister's.
This is my grandparents at their wedding in the early 50s. My grandma was almost 4 months pregnant but still managed to fit into this teensy outfit! The were married until she passed away unexpectedly in 2008. They spend fifty five years together, bickering, laughing and generally being amazing.
Looks like it was more of a tiny squeeze for your petite grandmother to fit in that lovely suit. Beautiful at a turning point in a beautiful relationship!
Dad was a Lieutenant Colonel in the Army Corps of Engineers. Mom & Dad got married at Ft. Lewis Washington after the war, and his men decorated this earth mover as their "carriage" from the chapel to the reception. This is a colorized black and white, and I especially like how they drew in a rainbow in the background.
