It may have happened almost a year ago but it seems like the biggest Halloween costume of 2015 is going to be Kim Kardashian on our #BreakTheInternet cover. Crowd-styling app WiShi collected data from over 200k users and predicts that the top five costume trends will be our Kim K cover (37%), Khaleesi from Game of Thrones (14%) and then perennial dress up favorites Sandy from Grease (20%), Cat Woman (9%) and Cleopatra (8%). They also helpfully provided some tips on how to style yourself for every look -- including a butt pad (which you can either use to enhance your derriÃ¨re or as a modest reveal if you prefer to go for our PG-13 cover). Although one thing they forgot? Baby oil. Be sure to stock up on lots and lots of baby oil.
