I was trying to buy a pea coat online, and I just reviewed my order and it turns out that I ordered a top coat (check link below). Is it a fashion faux pas to wear this kind of cloths with jeans and a nice sweater, collard shirt, etc. and not with business style attire. I am leaving to Germany shortly after the coat arrives, but I don't want to look like an idiot. Hope someone can help me out
