The unfortunate part is that a lot of these retailers are hard to find in brick and mortar spaces unless you're in a big city, so you may have to shop online. If you're wanting to browse in person in the casual to outdoorsy genre, I'd recommend REI because they really only sell high quality, sustainably made clothing brands.
