I bought this at Shimamura over 10 years ago. It's a tight skirt, so it's difficult to run in. I have to walk with small steps. There are no noticeable stains, and it has an inner lining. The part below the inner lining is see-through, but the inner lining itself is not! I think it's made of a material that doesn't pill easily! If you have any other questions, please feel free to ask!
