These are BLUE BLUE's classic PP550 jeans, made in kids' sizes with the same specifications. They're made of 100% cotton selvedge denim, probably around 13 ounces. They are likely around sizes 110-120. The actual waist measurement is about 55 cm, and the inseam is 48 cm. They have been worn after a one-wash, resulting in a very natural fade. The knee was torn once, but it has been professionally repaired, so they can still be worn. However, please understand that these are used items. Authentic denim
