Review on 👖 Blue Boys' Clothing for Shorts - GUNLIRE Drawstring Elastic Pockets by Isaac Simpson

I bought a size 18 for my tall teen, it's his normal size. The shorts have arrived and the tag sewn into the shorts has two of them "SIZE:____". The first was handwritten "12". The second was printed on a label and said "SIZE: 3XL". The shorts were too big for my son and I would like to change the order but have no idea what size to go. Is it size 12 and not 18? It doesn't make any sense to me. It is a pity. These are attractive shorts.
