Jessica McClintock Gunne Sax Millennium 2000 Two Piece Formal - Size 5 - Made in USA
This reminds me of I Dream of Jeannie. But is so of its era as well (I graduated this year!)
Long high waist skirt with zipper. Tie back top with sheer midriff and mostly open back.
Size 5: Bust 32-34" / Waist 26" /Hips 35" /Skirt length 40. 5"
Shell 100% polyester, Lining: 100% Acetate; Professionally Dry Clean only
Condition is good - the skirt's sheer upper layer had a couple open spots in its side seam so I hand sewed these 2 areas. This will need steaming.

This item is sold from an excellent, highly rated vintage boutique.
