This is a pleated skirt from GU. The color is gray, and the size is 150. I bought it but it didn't fit me anymore without me ever wearing it. Thank you. - The front of the waist is flat without elastic. - The back has elastic, making it easy to wear and giving a clean look. - The elastic is fixed at the back of the waist to meet JIS standards and prevent twisting. - The fabric is quick-drying and wrinkle-resistant. - It has a trapezoid silhouette and a mini length, and comes with inner pants. - Flat elastic with adjustment openings is inserted from the sides to the back. - You can adjust the waist by pulling out the elastic from the inside and sewing it in place yourself. - It's a cute design whether you tuck your top in or wear it out. - It has pockets on both sides.
