It's only fitting that the city that gave birth to the modern jean has the world's best denim store. At least, that's the idea behind Industrie Denim. Working in collaboration with over 80 denim manufacturers worldwide, the store offers a mind-boggling pants selection, as well as plenty of other accoutrements like shirts, bags, socks, and shoes. If you feel the need to try something on, keep a lookout for the "Booty Cam", which lets you know if things are looking as good from the back as they are from the front.
