I'm not a TV watcher so I did a little research on the matter. Julianne Hough is a actress who wore a Halloween costume to resemble another actress part in a movie. I would believe that she must have been impressed with the performance by actress Uzo Aduba to chose to impersonate her character. I watched the clip provided in this thread and I think she's very talented. So what I trying to point out is that I don't believe that it was meant to be malicious. I cut and pasted this quote that I found on E news on line. Weekly spoke to Cox at Monday night's TV Academy event celebrating LGBT characters, and while she agreed it was flattering of Hough and her friends to dress up as the cast for Halloween. I think it's great she likes our show. Crazy Eyes is my favorite character besides mine, too," she told the site. "But it's really interesting that she doesn't seem to understand. It's historically tricky in this country to re-create blackface. I'm not opposed to someone having their form of expression, but she seemed to be completely unaware of the historical implications going in, and I think that's problematic. If you want to make a choice like that, I think it's important to understand the historical context you are walking into."
She adds about people honoring Orange Is the New Black for Halloween: "It's so amazingly flattering. I don't know if that's a sign that you've made it, but it's wonderful."
Hough posted an apology on her Twitter last Saturday, insisting she was a huge fan of the show and of Aduba's. "It certainly was never my intention to be disrespectful or demeaning to anyone in any way," she wrote. "I realize my costume hurt and offended people and I truly apologize."
