I'm familiar with that company. They're revolutionizing shopping for jeans by letting you customize and personalize your jeans to fit you and you only, instead of buying mass-produced jeans that were really made for somebody else.
It's somewhat pricy at $135, but with its material and design customization options (I ordered a pair myself) it arguable ranks up in the high-end designer jeans category. In that respect, it's a pretty damn good deal!
I believe they also allow full refunds OR re-orders so they can alter your jeans if what you receive doesn't fit your size or taste perfectly. I didn't need to return mine, but they seem pretty legit.
Hope this helps!
