If you're living in US - you have way more options than in EU... :)

No particular order, just what's coming to my mind:

Iron Heart (their N-1 jacket is fucking amazing)

Buzz Rickson's (awesome coats)

The Flat Head (leather jackets)

Freenote Cloth (their waxed canvas jackets are amazing)

Rocky Mountain Featherbed

Dehen 1920

Lewis Leathers (don't confuse with shitty "Levi's Jeans")

Those are the first ones I can think of.

**Just don't but mass market shit.**

Because you lose out on everything, from quality and money, to your time, because after ~1 year the thing looks like crap, and you'll look like crap in it, and you need to spend time to go and buy more mass market shit.

Buy only quality stuff that ages beautifully and that will last you for decades. Obviously, no t-shirt will last you 10 years, but you also shouldn't buy that H&M shit whose clothes aren't designed to be washed.
