Jonathan did a post of the Diesel Black Gold Fall 2013 collection on the blog. The collection was inspired by psychedelic rock band on a Cosmic Tour and featured slim cut pieces and tailored outerwear. View some of the pieces below and you can read the original post here.
Welcome to the community Mike! Sounds like you have quite the denim collection. I'm in the DC area too! Have you ever checked out Denim Bar? I think there's one in Pentagon City, I've never had the chance to stop and check it out though.
