Olivia Palermo's been known to rock cocktail rings, designer suits and perfectly coiffed curls on The City. But that didn't stop the immaculately groomed social from hitting the red carpet last night in a flowy, bohemian style gown, with dangly earrings and stick-straight hair to match.
+ Think she's going through some sort of high-class hippie phase (a la M-K Olsen)? Or just cuttin' loose -- and letting her hair down? We're not sure, but either way, it agrees with her. We haven't seen Liv this happy/relaxed since, well, ever! Or at least not since Whitney came to town...
