As is the custom, most nominees and presenters whipped out a second outfit for the Vanity Fair festivities (style is a business, and never let anyone tell you otherwise). Some of them were for understandable reasons, like potential trampling, and others seemed to make no improvements on that front. Other gowns might’ve been worth the risk of being stepped on just so that we could all see them longer. Come take a whirl through this and see who you think was right to make the swap (hi, Allison Williams),  who should’ve stuck to her original plan (Margot, Paz), and who should’ve just bought a bootleg time turner and tried the whole night again (sorry, Emma).
