Vintage Gunne Sax Style Dress

Beautiful collectors vintage dress with exquisite lace details. No namebrand on tags, but it says made in USA. Listed as a size 9 but model wears a size 2 and it won't zip up. Please refer to measurements. Perfect condition except for a tiny spot shown in second to last picture. May be removal but I have had the dres cleaned. Material: 50% polyester, 50% cotton Measurements: Bust 15 in laid flat Empire waist 12.5 laid flat
