Trying to change my style of clothes?

im trying to stray away from those burned-out polo shirts and those affliction tee's That's all I ever wear.. besides ACU's. I was recently watching the movie Dinner for Schmucks and I got to be honest, I like Paul Rudd's clothing style. Does anyone have an idea of the type of clothes he wears? Name the brands. HE pretty much repeats his styles in everyone of his movies.
