They grow up so fast. As of yesterday, one of our favorite blogs, the Sartorialist, celebrated a milestone birthday—5 years old (just like us)! From snapping street style photos of uber-stylish Manhattanites to shooting for mags and major fashion campaigns, what started out as Scott Schuman's simple side-project has rocked the fashion industry and inspired bloggers, stylists and designers alike to get in on the action. Let's give the dude five cheers for getting our men all dandified. We hope Scott and his main squeeze, blogger Garance Doré, celebrated breaking out of toddler-hood, we know we sure did.
