This is a jumper skirt I purchased from MUJI♪ The length can be adjusted in two stages with buttons, allowing you to wear it for a long time^_^ It can be paired with short sleeves, long sleeves, or sweaters, making it very versatile♪ Please purchase only if you understand that it is a used item. Thank you very much m(_ _)m I also have many other items for sale, such as GAP and ZARA. Please take a look^_^
