The Barbie-themed Halloween costumes are already starting to roll in, and Olivia Wilde is the celebrity to get them started.

On Sunday (October 8), the Don’t Worry Darling director and ex Jason Sudeikis hosted a Halloween-themed party for their daughter Daisy in Los Angeles.

She dressed up as Ryan Gosling‘s character Ken from the movie, and it was a perfect costume!

For her costume, Olivia went with the neon-bright look that Ken and Barbie (Margot Robbie) wear when they arrive in the human world. Her outfit included pink, orange, blue and yellow board shorts with a vest and visor.

In the movie, Ken is wearing rollerblades. However, Olivia opted for a pair of Vans. She wore her hair in braids and finished off the look with dark sunglasses.

Jason went in a different direction for his costume and dressed up as a king with a crown and all-green outfit.

It seems like a very safe bet that Barbie will be one of the most popular Halloween costumes this year, and we’ll find out very soon.

In the meantime, did you know that all of these scenes were deleted from the movie?!
