Depends on your definition of custom & whether this is a men's only establishment. Besides Leddy's I can think of Drysdales in Tulsa, Rockmount Ranchwear, Denver, Cheyenne Outfitters, etc. But they might not be custom enough for your definition. You probably need to go onetime to the National Western Stock Show in Denver or the High Noon Old West Show & Auction in AZ. You can do a lot of shopping at either show.
