Well constructed clothing has become a rarity these days. While I offer no all-encompassing solution...I can offer a new line that suggests attention to detail and focus on the craft. I originally heard about The West is Dead from Malibu Magazine (seen here). Designed, sourced and manufactured in Los Angeles, with overt lines to classic American construction. You even get a buffalo head nickel on each garment hang-tag (like, a real one...from the 20's and 30's...dang). If that's not a resurgence of American quality and craftsmanship, than point me in the right direction.
The line is slated to hit stores in April, but feel free to follow The West is Dead's site (found here) for up-to-the-minute details on their launch.
