Okay, new question: I typically wear suits everywhere, if I want to dress down I just remove the tie and unbutton the top two buttons. I feel better when I'm dressed well, however sometimes I just want to jump out of my East Village apartment and run to the store or to the gym. It's a little impractical that I 'dress' to do this - however (niave) this is just what I've been doing. I've got a little bit of a belly (yes the gym is helping) - but I don't feel comfortable walking around with just a shirt, button down. I think the suit coat helps give my body some structure. I've seen some guys wearing sport jackets - or something close - I'm not a huge fan of the nautical buttons - but am open to this kind of thing - is this what you guys wear? What are the rules on sport jackets - if I grab one with stripes then my pants and shirt should be plain? What else do you suggest to dress down? Thanks!
