This is a cotton long skirt from Samansa Mos2. It's 100% cotton and quite thin (sheer as shown in images 2 and 3), so I think it's excellent as a petticoat for the summer. There's a noticeable stain on the inside. It's not a concern if worn as a petticoat, but please refrain from purchasing if you are sensitive to such things. #samansamos2 #sm2 #サマンサモスモス
