Sometimes one stunning red-carpet-worthy gown just isn't enough - and in the case of Naomi Watts (and eight other A-list ladies), the Oscars provided the perfect excuse for slipping into numerous evening dresses. Watts first stunned in a silver-sequined Pucci creation for the Vanity Fair afterparty. The quick-change "movement" allowed us to see more stellar styling from some of our favorite starlets, and most of all, it added an extra dose to the night's all-out glamour quotient. See who else donned more than one look on Oscars night, and let us know which ensembles were best.
