I purchased this from Sunny Hug on Rakuten. Waist: 64 cm I bought this for my child's junior high school entrance exams and they wore it twice. By the way, they passed! I hemmed the pants myself, shortening them by 23 cm. Thank you! ^ ^ I think the size is around 150. Pants for all seasons, standard school uniform for boys, black slacks, no pleats, slim fit, quick-drying, lightweight, washable.
