The sisters (and designers behind the Twenty8Twelve line) will play hostesses at the Prince outpost of Intermix with special guest Alejandro Ingelmo. Essentially, you can now be sure that there's no way you'll even get in the door -- or possibly even make it down Prince Street at all -- the place will be so packed.
Best of all, the store will also host a special Art Battle, in which two fledgling artists will compete by painting two Intermix mannequins (auctioned off at the end of the evening).
