Vintage 1970's Small? Wedding Gown Romantic Tiered Floral Lace Boho Beaded

Vintage 1970's Small? Wedding Gown Romantic Tiered Floral Lace Boho Beaded. Great condition aside from some small staining on outside and some staining on inner lining! The zipper is a little finicky and is crooked in spots but still functions. It doesn’t zip on my dress form but does otherwise! Please see all pictures! Please note that there is no size so I’m estimating it to be a modern size small based on measurements below! Measurements: Armpit to armpit: 15” Sleeves: 22.5” Waist (no stretch): 12.5” Length (not including train): 67” Themoderngirl
