Uniqlo size 150 long pants. The waist is adjustable with elastic. Made of stretch material, so it stretches well. There is a stain on the left inner thigh... Please check the photos. The color may differ from the actual color due to the lighting... I think the 7th photo is the closest (although only a part of it is shown...) Please understand that these are used items worn by a child, and that they have been inspected by an amateur. Please purchase with this in mind.
