This is a Gunne Sax by Jessica McClintlock. Satin is acetate and nylon.  Lace is nylon  Recently handwashed carefully.  It is cream colored. Tie in back. Lacing in front does come loose.  I wore it for dress up day at school with a hoop (dress is way too long for me.  Has been in closet for years.  

It is handwash only.  Measurements: shoulder to hem is 58.5", armpit to armpit is 15.5", high waist is 13" side to side.

May be a small water stains near the hem.

If you looked at this when it had the two small places on a seam, I had them repaired by a professional alterations place.
