Top 20 best celebrity Halloween costumes of 2015 – You need to see #1! (With Pictures)

16. Gigi Hadid

The biggest downfall with Gigi Hadid’s Halloween costume, is that it probably lead to Grease being stuck in everyone’s head for the rest of the night. Gigi attended Heidi Klum’s Halloween party this year and her outfit did not fail to live up to the hype of the event. Gigi donned the classic look of Sandy fromGrease, including the curly hair and an iconic cigarette. Granted Gigi is a model, and there is no proof of whether she can sing or not, but thankfully it did not take away from the overall look. There is no word on whether there was a John Travolta look alike also somewhere at the party.
