Dress Fitting For The 2011 Oscars: Oprah Looks Back (VIDEO)

It's the biggest night in Hollywood, when all the stars are dressed to the nines. But what does it take to find the perfect Oscar-night dress? Oprah takes a look back to when she was preparing to be a presenter at the 2011 Oscars. In this behind-the-scenes clip, she works with a representative of designer Zac Posen to create the perfect glamorous look -- corset and all.

"I wanted a dress that was beautiful, but that wasn't saying, 'Hey, look at me, look at me, look at me,'" she says. "Because I think sometimes people go way over the top."
