Taylor Swift Won Halloween With Her Adorable "Frozen" Costume

    No, she didn't go as Elsa.

    While Taylor Swift has always been pretty good at Halloween, this year she really went above and beyond.

    Last year, she rocked a comfy-cozy pegacorn costume and earlier this week she shared a #TBT to the year she went dressed as a Teletubby.

    Not only did the pop star dress up as Olaf from Frozen during a concert in Tampa, Florida, on Saturday night...

    She also turned her dancers into reindeer...

    Here she is singing "Style" with one of her reindeers because why not.

    And then invited Idina Menzel — aka the real-life Elsa — to join her on stage to sing "Let It Go."

    Best 1989 squad yet.

    Some Halloween celebrations are worth melting for.
