You might have to do a double take when you see the outfit Taylor Swift [1] wore for the Vanity Fair afterparty following Sunday night's Oscars in Los Angeles. After walking the carpet with her BFF Lorde [2], Taylor posed solo for photographers in a sexy, edgy look from French designer Alexandre Vauthier. The gown was a combination of deep v-neck and thigh-high slit; it's safe to say that there was plenty of skin on display. Taylor stuck with the golden theme of the Academy Awards, finishing her look with sky-high gold Giuseppe Zanotti heels and Lorraine Schwartz jewels.
