There’s no doubt that Katy Perry has already won Halloween with her transformation into Hillary Clinton, but apparently she wasn’t even close to being done with the fun. Hosting an epic Grease-inspired sock hop party this past weekend for her 32nd birthday, Katy went all out to take her guests back in time.

Katy wore a mile-high yellow bouffant and a matching, totally retro yellow and black outfit that perfectly suited her role as principal of “Hudson High” (note: Hudson is Katy’s real last name).

Party-goers found themselves wandering through a cafeteria (with yummy eats for those willing to wait in line), a detention room (yikes) and a party-ready gym complete with performing Elvis and Marilyn Monroe impersonators.

Celeb friends like Orlando Bloom got into the vibe with costumes that totally rocked the theme — yep, that’s him in short-shorts and boldly blonde hair.

Some super flexible folks found themselves caught up in a giant game of era-appropriate Twister.

And what sock hop would be complete without a massive poodle cake, amirite?
