I got this gown set from a very nice, compos mentis, older woman. She told me it was a bridal gift to her dating from her 1952 wedding. There is a long gown, cape-like jacket and one garter. Tula is the label. The gown has a back zipper and it has different sort of plastic teeth. I've never seen such a zipper from the early 50s--can this be from 1952?
