Olivia Wilde
A modern twist on the '20s flapper dress that only Marchesa could provide, the white, fringed frock worn by Olivia Wilde last night was a wonder. The stunning 3D flower details only took the dress to the next level and complemented by a simple beauty look - a sleek pony and sharp cat eye liner - the ensemble stayed chic without going overboard. Add those elegant emerald-cut pink spinel and diamond drop earrings from the new Blue Book collection and we have ourselves a #BestDressedGuest.
