I suppose this is called "grunge"? Leather vests are interesting... I know I like slim-fitted menswear vests, but puffer vests just make people look like tourists, and some vests make you look like a kindergarten teacher. Leather vests, on the other hand... I guess they have a biker vibe? Anyway, I like the leather paired with the texture of the sweater (which I like by itself--really great, gritty, rough-looking texture). I'm not sure I could wear purposefully-sloppy jeans, though.
