There were so many fabulous gowns at the Vanity Fair Oscars afterparty, but we're truly loving Reese Witherspoon's sparkly cocktail dress. She looked like a modern-day princess in this glitzy design covered in twinkling jewels. We like that the star wore diamond-encrusted heels to match her dress. All she needs is an enchanted carriage to pick her up at midnight! Take a look ahead at all the details of this fun little dress.
