American Apparel had denim shirts in every wash from dark to light an in between, but they aren't western in cut or styling. There are usually a lot of cool denim western shirts on eBay if you don't mind...
I sniffed Bruno Fazzorlari's Lampblack at the Scentbar a few weeks ago - it's a vetiver and it's pretty intresting. Also I think everyone should try Goutal's vetiver if you can find it - it's got a very salty, seaweed vibe that puts you right on the beach.
Not everybody wears it that way. I wouldn't.
This reminds me of Thom Browne - I think it was GetSmart that bought a Thom Browne suit, but tailored it to his own liking, and it looked awesome. You don't need to wear it like Thom does, nor do you need to size down on your EG jackets. But anyway, CD doens't only wear EG, this was a general comment about how to think about silhouette and your own body type.
I think one recurring thought I've had about your fits is that you have your style and pieces fairly dialed in but you could work on silhouette. The way you wear these pieces tends to shrink your top and emphasize the bulk in your legs. I think the simplest way to address this would be finding broader-shouldered jackets, or looser fitting volumes for the top half. Sizing up one and then tailoring the sleeve length might even do the trick.
The point is, this is a style forum, for people who are interested in fashion and style. Your picture is off topic, it's not something the group can learn from, comment on, whatever. If you're interested in the topic - style/fashion - and want to contribute, that particular entry isn't helpful.
