Boy’s jean jacket NWT 14-16 18 grey sleeves

Runs very large. New, never worn from Neiman Marcus kids department. Brand new by brand PX. A Neiman Marcus exclusive brand I think. I ordered for my 10 year old son but it turned out to be extremely big: it says medium but more like an XXL and could probably fit as a men’s small maybe, or a size 16-18 boy. Removable hoodie. Fleece-lined sleeves and hoodie.
