Former Project Runway designer Michael Costello is having a maaaajor moment, ya'll. The newest favorite among the young, hot celebrity crowd, Michael's designs are coveted not only for their expert tailoring and bold, saturated hues, but for their unmistakable glam factor, as well. Always sexy and incredibly chic, MC gowns and party dresses showcasecurves and a fierce attitude at once -- is there anything better? From Khloe K.'s black sequined birthday party stunnertothis over-the-top Beyonce leotard, it's safe to say Costello's designs are among the hottest to hit the red carpet this year. Since the debut of THAT white hot, sheer lace dress from the Grammy's, it seems Costello's designs have been in high demand. We love a good success story, and it doesn't get much better than a Project Runway reject turned high-fashion guru.

A star like Beyonce needs no introduction, but she does need someone to dress her for her and hubby Jay-Z's On the Runtour. Employing the help of fashion god Tom Ford, Versace and now, Costello, Beyonce's tour looks are always two stepsahead of awesome. While we love, love, loved the two-piece mix floral number he designed for her, it's the black, bell-sleeve leotard we can't stop oogling. The ideal combination of glamour and goth, this look is one sure to blow those legions of Bey fans away.
