It's a sheer chiffon layer with the polka dots over an opaque inner lining of acetate.

Matching belt, short sleeves in a slightly dolman shape. Nylon zipper in back.

Excellent condition. There is one pinhead sized hole in the chiffon layer on the bodice ( a brooch would cover it) and an old repair under one arm at the seam.

The color may have yellowed a touch over the years too.

Measurements when lying flat. Doubled at bust, waist, and hip.

Armpit to armpit across bust: 37"

Waist: 28"

Hips: 39. 5"

Shoulder to waist: 14. 75"

Shoulder to bottom hem: 39. 5"
