1. Angel Wings
True life story: While we were at Coachella, minding our own business and trying to listen to MGMT, a gaggle of girlfriends all wearing big, life-size feathery angel wings skipped past. It didn't make all that much sense, but we get that there is a certain type of joyfulness surrounding a festival that elicits carefree accessories. Wear them if you will, but please, shed them once you head back to civilisation.
