This is a pleated long skirt from GU. It has a full lining, so you don't have to worry about it being see-through. I inspected the pleats, spreading them out to check for stains, but I didn't find any, especially. However, please understand that this is a personal inspection, so I would appreciate your understanding. m(_ _)m The waist is elastic. I think this item can be used for casual or dressy occasions, and it's suitable for many seasons and places ^ ^* (I will turn it inside out to protect the pleats before shipping.) Thank you.
