For your Ebay adventures we have a very lovely pair of sweatpants from Aerie in a size Small. They are a soft velour fabric of 78% Cotton, 22% Polyester. They have elastic at the waist and a drawstring. The legs are flared. They are in excellent condition. The approximate measurements are as follows:

Waist: 15 1/2" across, will stretch to about 17" across, Rise: 11", Inseam: 30", Length top to bottom along the side: 40", Leg opening at the bottom: 11" across.

This item is from my smoke-free home. We do have a cat, but she is not allowed to wear our clothes :-) Please ask questions and/or request more pictures before bidding as I don't do returns. 

Thanks for looking!
