An homage to "Black Swan," a boob-baring gown and a sexy silk robe -- the stars are rocking all the wrong trends this week!

Olivia Munn may have gone to see the ballet, but the actress looked like she was ready to hit center stage at the American Ballet Theater's Opening Night gala on Wednesday in New York City.

The "Newsroom" star seemed to be channeling Natalie Portman's Oscar-winning role in "Black Swan," as she posed for pictures in a black Lanvin feathered mini with shimmering accents. She even slicked her hair back into a ballerina bun.

Sorry, Olivia -- this look belongs on the stage only! 

Maitland Ward has been creating some buzz recently for what she's wearing -- or not wearing -- on the red carpet.

The former "Boy Meets World" star raised some eyebrows at the Adolfo Sanchez fashion show in Los Angeles on Monday, where she showed off her nipples in this daringly sheer dress. The worst part? The cascading train looks like it's coming out of her crotch! 

And, Jennifer Hudson raised some eyebrows for putting her bra on display at W Hotels' "Turn It Up For Change" Ball benefiting LGBT equality on Tuesday in New York City.

We applaud the singer for trying a new spin on the little black dress, but her satin wrap style looks more like a robe.

But, these ladies weren't alone -- click "Launch Gallery" above to see more of this week's worst dressed stars.
