Since the Oscars are all about the dresses and suits (in our books, anyway), we can think of no better way to kick off one of our favorite annual festivities than with a jam-packed night of high style bashes. And last night saw not one, but three of fashion's best brought together when Angelina Jolie in Saint Laurent, Brad Pitt, and a Jonathan Cohen-clad Lupita Nyong'o joined forces for the 12 Years a Slave pre-Oscars event. Also keeping busy were Cate Blanchett, Anne Hathaway, and Taylor Swift, who all brought their A-games to last night's parties.
Earlier in the week, Bulgari's Decades of Glamour event was hosted by an Altuzarra-clad Naomi Watts and attended by her chic set of friends, who included Kate Hudson and Olivia Munn. While the jeweler looked to Old Hollywood, Vanity Fair had its eye on the future with a young Hollywood guest list that boasted Kiernan Shipka, Jena Malone, and Zoey Deutch. A look at the most stylish stars who've attended Oscars preparties, below.
