I did have some 40s patterns and appropriate fabric in my stash. In fact, the only thing I had to purchase for this dress was the zipper!
I did use metal buttons because they were super cute roses and I rationalized that in 1940, the war had barely gotten started so rationing wouldn't be as huge of a deal yet (especially here in the states) and a seamstress might have such darling buttons in her stash already.
I accessorized with American Duchess 23skidoo shoes. Since it's an early 40s dress, 30s shoes are ok. ;) Plus I love the fact that they are white!
I also popped with red accents but the great thing about this dress is that I can wear what ever color accessories I feel like!
