Lily Collins and Jenna Dewan snagged some new baubles for charity! Film producer Hilary Shor and jewelry designer Jessica Robinson hosted a dinner in support of Dress for Success, and offered guests the chance to take home an item from Robinson’s new collection for every gently-used piece of jewelry they donated. “I’m wearing her necklace and rings,” Collins told us. “I’m super excited!” Dewan (in Rachel Roy) also draped herself in Robinson jewels, describing them as “fabulous!” See more stars at last night’s hottest parties in the gallery!
