This November marks W's 40th birthday! To celebrate, the magazine wrangled up some of the biggest names in Hollywood (Scarlett Johansson, Keira Knightley, Rooney Mara and Mia Wasikowska, to be exact) and dressed them up corresponding to each decade that the publication has been in business. Scarlett's new 90s look was certainly the most surprising, what with the nose ring and all, but you can check them all out by clicking here!

Keira Knightly (looking almost unrecognizable up there with her bleached, slicked-back hair) is supposed to represent our current era, AKA the aughts. Do you think the look is accurate? I say that it seems to be fairly spot-on (aside from the hair), but only time will tell. Head on over to the source to read even more about W's interviews with these lovely ladies! [via Fashionista]
