These are long leggings from MUJI. They have been worn. My child is slender, so I adjusted the elastic waistband to be a little tighter. If the waist is too tight, please replace the elastic cord to fit your child's size. Thank you for your understanding. - Size: 130 - Material: 96% cotton, 4% polyurethane - Color: Gray - Pockets: Yes Thank you for looking.
