I don't see any noticeable stains, but there is a sense of use... Please check the condition in the photos. m(_ _)m The size is L, but I think it can be worn by a child around 140cm (individual differences apply). Please refer to the measurements❣ Size: Shoulder width approx. 40cm, sleeve length approx. 55cm, body length approx. 61cm, body width approx. 50cm❣
