Call it our raison d'être. Or maybe it's an obsession. But, since the dawn of R29, we've been on a serious hunt for the next Rodarte/Alex Wang/Prabal, sussing out each class of new designers for the Next Big Thing. Because nothing excites us more than the cycle of discovery: an incredible debut lookbook, the post-FW critical fawning, the first well-placed editorial, and then, the very fashionable frenzy.So, we went ahead and made our predictions for the class of 2012.
