This.A denim jacket wouldn't suit me in a million years, I'll stick to band/movie shirts.
Personally I think they look so fucking stupid, haha. Just really, really, do.
Denim vest is cool! And it also fun when total strangers come talk to you on gigs about bands in your vest, for example my Sacred Reich backpatch has gotten me couple beers, people wanting to buy me for having so great band in my vest
