Andy, your pictures only prove Tommy's point, and I agree. That looks terrible.
Also, argyle is not the same as plaid. Neither is gingham. Those BR models aren't wearing plaid.
Also, I already bought the sweater on BR model one for the bf, but I was wanting more of a dark brown blazer for him. I think the black might be too dark, but it looks fine on the model. But my boyfriend always wears black, thus the buying him new clothes, so I kinda wanted to get him away from that. Thoughts? Is dark brown gonna look ugly/too wash out?
