Vintage Jessica McClintock Bubble Dress

Very fun vintage Jessica McClintock for Gunne Sax strapless dress. Silver embellishment and beading on the bodice. Full ‘bubble’ skirt. The dress says size 3 but her collection for Gunne Sax runs much smaller. My dress form is a size zero and I couldn’t fully zip up the back. This is definitely closer to a 00 so that is the size I am listing.
