I'm not sure if this is a slip or a skirt. It seems too pretty to be worn under something. On the other hand it is quite see through in places. It is made of white silk and netting. It is in excellent condition with no holes or stains. There is no size label on it but I would say it would fit a size 6-8. The elastic waist is 24.25" when not stretched. The length is 32".
