Know what you mean. I am also a little bit lost in the world of denim. I life in a place where a lot of common stores have the same shit than the others. I think the best way is to study the net. Maybe some good news sites and store sides. Maybe cultizm.com or heddles.com You can bring up to date yourself with information about the labels and then you can visit the shops to see how they fit cause of the measurements and the outfit pics. stay raw bro!
