APC makes some of the best raw denim jeans out there, i have a pair of the hipsters, if you decide to wash them, you should first get them dry cleaned, then use on the the recipes that APC gives you. I found the best way with them is cold water, a bucket and some woollite, and hang to dry..and remember they will shrink about 2 inches in length.
Other great high end jeans out there are;
Nudie
Rag and Bone
Earnest Sewn
Acne
A good place to buy these too is
