All the Celebrity Style from the 2012 Trevor Live Benefit

It was no ordinary Sunday evening in LA, thanks to The Trevor Project's annual Trevor Live benefit and the star-studded crowd that came out to support it. Among the guests? Katy Perry — who was also honoured at the event — stepped out in a sparkly nude Marchesa gown, Zoe Saldana wore a blush-toned fit-and-flare cocktail dress with a killer pair of embellished ankle-strap pumps, and Glee's Naya Rivera (one of the night's performers) chose a lacy Dolce & Gabbana LBD. Along with the more traditionally glamorous fare, some starlets opted for an edgier approach to red-carpet dressing. Just look to Ashley Madekwe's structured Kimberly Ovitz dress, Rashida Jones's bold-hued pantsuit, and Brittany Snow's thigh-high Halston slit number for the chicest kind of evidence.
