These are kids' leggings in size 150, made with UNIQLO's HEATTECH material. I'm selling them because my child has outgrown them. There's a slight fraying of the elastic thread in one area (see photo), but it was barely noticeable until I checked closely. Please refrain from purchasing if you are concerned. m(_ _)m - Brand: UNIQLO - Model Name: HEATTECH - Size: 150 - Waist Size: 57-63 cm - Suitable Height: 145-155 cm Thank you for looking.
