This Halloween, do not dress up as a "Native American Princess" or a "Bandito" or a "Sexy Geisha" or any of those other stereotyped costumes from Spirit Halloween. For the love of god, there are so many thing you can be and those costumes are so freaking expensive, just don't.
And I don't know how it is that I have to say this even but DON'T COLOR YOUR SKIN TO BE ANOTHER RACE. NO BLACKFACE. NO REDFACE. NO YELLOWFACE. NO BROWNFACE. NO.
