30 Celebrity Halloween Costumes That Will Make You Do A Double Take

The dedication is real

There are two types of people in this world: those who don't do Halloween at all, and those who do the absolute most. And even though we've seen some pretty horrible costumes ahead of the holiday today, our favorite celebrities came through this past Halloweekend to showcase some of the very best. Some so good, you might even do a double take.

It's hard to imagine this year topping last year's incredible costume roundup, but celebs like Demi Lovato and Kehlani make a pretty strong case for 2017 being the best Halloween ever.

Decide for yourself and see the 30 best celebrity costumes this year, below.

Kehlani as Flaca in Orange Is The New Black is probably one of the most convincing costumes of the year. It was so good, Flaca herself (played by Jackie Cruz) reposted the photo with the caption, "Never felt so cool. 100 % #Flaca approved!"

Laverne Cox opened up about her transformation into I Dream Of Jeannie character Major Nelson in a heartfelt Instagram post. She writes:Just a year ago I might not have been comfortable enough to dress in male drag for Halloween. This was kind of a big deal for me. Getting dressed definitely brought back some major trauma. But after all these years I know my womanhood is more than clothes. It's always been spiritual. Halfway through the night I did have to unleash my femme. She can never be contained for long.

Trans is beautiful. And that costume is magnificent.
