13 years ago the founder of SH liked wearing his jeans from a raw state, and noticed that all the stone washed jeans available then weren't to his liking. Sure, they were faded, but not in a way like you would've worn them yourself. He then invented the 'Magic Wash'. All the jeans are distressed by hand, creating one-of-a-kind washes. I gotta say I'm impressed with the washes, they look pretty authentic. Still, it's not the 3d effect you get from wearing jeans yourself.
Also, Spotted Horse offers a Make Over service. You can bring in your own unfaded jeans or denim jacket, and let them customize it for you.
