Marc Jacobs' Birthday: 6 Reasons to Love the Designer

Marc Jacobs before the Louis Vuitton spring 2014 runway show at Paris Fashion Week

Because Marc sometimes goes to work in his pajamas and carries his stuff in a dopp kit. Because he can.

Because there ain't no party runway show, like a Marc Jacobs runway show. Remember the glorious sets he created for Louis Vuitton? The mod escalators, the train pulling into the station, er, venue, the tent outside the Louvre, and the freakin' carousel?! Thank goodness he has his own line—still dying over postapocalyptic beach scene from spring 2014—to continue the mind-blowing fun.

Because even though his designs may be on the aspirational end of the spectrum, Marc still makes high fashion accessible to all through innovative social media, like, live-streaming his runway shows (everyone's FRONT ROW, yo) and casting his fall campaign via Instagram.

We love you Marc! Happy birthday! What's your favorite Marc moment?
