It's a skirt and pants combination. The waist has elastic on the sides and back, and is not adjustable. There is one pocket on the right side. Purchased at Ito-Yokado. My preferences changed, and I outgrew them before I could wear them even once. The material is suitable for spring and summer. Size is 150. It is an unused item with tags, but it has been stored at home, so please refrain from purchasing if you are concerned about minor details.
