Let's just establish this rule once and for all:  If you're white, DON'T WEAR BLACKFACE.  Whether you think you're being offensive or not, YOU WILL OFFEND.



JULIANNE HOUGH may have learned this lesson over the weekend, when she went to a Halloween party as the character Suzanne "Crazy Eyes" Warren from the Netflix prison series "Orange Is the New Black".



Crazy Eyes is played by African-American actress UZO ADUBA . . . and Julianne decided to do the whole authentic skin color thing . . . which, predictably, caused the Internet to EXPLODE.  (Check out pictures of Julianne and the REAL Crazy Eyes here.)



Julianne has already issued her apology . . . quote, "I am a huge fan of the show 'Orange Is the New Black', actress Uzo Aduba, and the character she has created.



"It certainly was never my intention to be disrespectful or demeaning to anyone in any way.  I realize my costume hurt and offended people and I truly apologize."
