Olivia Wilde is in the new Vanity Fair Hollywood Issue, dressed as... I have no idea, some old timey Hollywood dancer I guess. Or Vegas maybe. I don't really care to be honest, I just wanted a reason to put up that .gif.
Her breasts are so much bouncier than I imagined, and I assure you, I have imagined how bouncy they may be. A lot. Probably a week or so if you added it all up.
