Andrew Toth/WireImageEvery Halloween, Hollywood's finest step out in the most dazzling costumes and this year proved to be absolutely no different.
Between saber-swaddling Jedis and a Coming to America blast from the past, A-list names like Katy Perry, Kendall Jenner, and Reese Witherspoon proved they are capable of major transformations even when they're off their respective sets—and the inspiration was boundless.
Celebrities used everything at their disposal to influence their costume selections this year, from iconic musicians to a newly-infamous city garbage rodent. While some opted for spooky, others settled on pure comedy as they hit the streets to showcase their latest—and possibly greatest—creations.
