Ashley Greene: Polka-Dot Pretty

Ashley Greene shows off her pearly whites as she arrives at the NYLON & YouTube Young Hollywood Party held at the Roosevelt Hotel in Hollywood on Wednesday night (May 12).

The 23-year-old actress, wearing a cute yellow polka-dot mini dress by D&G, co-hosting the evening with cover girls Vanessa Hudgens and Portia Doubleday (also pictured).

FYI: Ashley accessorized with an oxidized sterling silver and rose cut diamond ring paired with oxidized sterling silver and rose cut diamond mini chain link earrings, all by Irit Design!

Ashley will be honored tonight at the 2010 Young Hollywood Awards as Style Icon.
