Sally Hansen has been making a very strong case for being the most fashionable nail polish brand. For Spring 2012 they continued their designer collaborations with Alexander Wang, Prabal Gurung and Tracey Reese; some of the most talked about shows of New York Fashion Week. So far this season there isn't a hotter designer to align yourself with than Prabal Gurung and the iridescent purple shade that they created together is just as buzz-worthy. Wang went for surprisingly subdued versions of patriotic red, white and blue while Reese opted for juicy brights. Overall a hugely fun success and I want them all.
