At the Young Hollywood Awards in Hollywood on Thursday, the under-30 set in TV and movies brought their A game on the red carpet.

Ashley Greene, 25, who was the evening's emcee, chose black tailored trousers and a strapless Donna Karan bustier top. She finished off her look with tousled waves, peep-toe heels and several bracelets.

"Getting ready for the Young Hollywood Awards! I’m really excited and a bit nervous to be hosting! Wish me luck!" the Twilight Saga actress tweeted pre-show.

Sophia Bush, 29, stepped out in a black and white cocktail dress and black point-toe pumps. Her clutch, a lips-shaped purse, proved to be one of the most stand-out accessories on the red carpet.
