These are my grandparents! I used this picture for my save the dates. I think it's one of the most beautiful pictures I've ever seen!
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!
