We've all been there.
We've all looked back at an old photo of ourselves at a costume party, red solo cup in hand, pre-2008- recession smile spread across our faces. "Why would I wear that costume?!" we think to ourselves. Even Justin Trudeau has been there once...or twice...or three times. But in most cases, you just can't believe you thought those cat ears were cute or that you decided "sexy Stay Puffed Marshmallow Man" was a good costume idea. Most people don't look back at old costumes and think, "Wow! That was pretty racist and/or culturally insensitive!" You know why? Because of all the things in the world to dress up as, why dress up as something or someone that's racist/culturally insensitive? Because you're lazy and racist and culturally insensitive, that's why! Here are 13 times celebrities were just that for Halloween.
