Size is S to M. It's a black petticoat to prevent skirts and dresses from being see-through. It fits most skirts. I have tried it on. I am borrowing the tag. Please read the profile before purchasing or asking questions. I will not answer questions that are already stated in the profile. I will not trade with users who have negative feedback, so please refrain from purchasing if you have many negative reviews. I have tried it on, so please refrain from purchasing if you are concerned. It will be compressed for shipping, so please be aware that some wrinkles may occur. I do not negotiate prices or reserve items. I will not respond to price negotiation requests, so please understand. I do not accept any shipping requests. Shipping will be done within 4-7 days when possible, so I cannot answer questions like "When will you ship?". I am working, so I cannot respond immediately. I cannot accept any individual shipping requests or reservations. There is no need to contact me with messages like "I bought it" (notifications from the system). It would be appreciated if you didn't contact me, as it will be displayed on the list.
