Vintage 1970’s sundress

Vintage 70s sundress ( likely homemade) in great condition. Light and airy, perfect for hot summer days. It’s just a little too snug for me (see pictures) otherwise I would never part with it. It has a fair bit of stretch in the bust, but I stress the seams and zipper and I don’t want to ruin it. You can safely add a few inches to the pictured measurements. Measurements are approximately Bust 12” + stretch Empire waist 11 1/2” + stretch Hips are fairly open Length 43” Approximately an xxs or xs
