Halloween is one of those rare equal-opportunity holidays: one that kids and adults can mutually delight in, unabashedly.
That's exactly what we saw many of our favorite celebrities do over the weekend — get unabashedly silly and creative with their Halloween costumes. And let's face it, seeing what each of them decided to put on is something of a window into what they're thinking, right?
Here's a collection of some of our favorites (but really only a small sample) of the awesomeness that roamed the streets on Oct. 31!
