Affordable and classy
Size: Medium, Color: Light Brown, Size: Medium, Color: Light Brown
I have five stars even if the best was a little short. I have a tall boy and the rest is totally worth the money. Fit was as marked aside from vest which is higher on the chest than necessary. It was comfortable for him and durable. Gonna keep for any need in the future. He wore it to prom and it was awesome.
