Show stopper!
Size: X-Small, Color: Blue-2 Pieces, Size: X-Small, Color: Blue-2 Pieces
This jacket is everything! My son wore it to his football banquet and it looked amazing. I was worried because he is big for his age and although he can wear men sizes, they can sometimes be too long in the arms. This jacket did not disappoint. It fit his arms well, buttoned up nice and was a great length. It was a nice feel and was not overbearing and thick, but made well. He did a lot of moving around but had no issue with feeling tight it’s certain movements or any rip. I would definitely recommend, money well spent. For reference, my son is 5’1 and 125 pounds. We got a size XS.

Not even close on the size
Size: 3X-Large, Color: White
Size is not even close to correct. Ordered a 3xl but the actual size was closer to a XL or even a large. Be wary on the sizes. They are not accurate
