Hollywood pulls out all the stops when it comes to dressing up and Halloween is no exception. And judging by Instagram, the holiday is always a smashing success.
In 2016, some families opted for group costumes: Beyoncé and Blue Ivy were Janet Jackson and Michael Jackson while Jessica Simpson and Eric Johnson dressed up as Danny and Sandy from Grease in all-black ensembles and '60s hair. Kate Upton and Justin Verlander also took on the unforgettable characters. Gigi Hadid reminded us that you can make Halloween chic, as she transformed into a Cub Scout, and Heidi Klum, who always hosts the hottest costume party of the year, multiplied herself—literally.
