There鈥檚 no doubt that Katy Perry has already won Halloween with her transformation into Hillary Clinton, but apparently she wasn鈥檛 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 鈥淗udson High鈥 (note: Hudson is Katy鈥檚 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 鈥 yep, that鈥檚 him in short-shorts and boldly blonde hair.

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