Lady Gaga
is no stranger to making a fashion statement, but she's committed a series of fashion faux pas this week!

Gaga seemed to be getting into the Halloween spirit early, stepping out in London in a very sheer black top and black peacock feather head piece. We will give her a round of "Applause" for originality but not for her fashion sense.

The pop starlet also was spotted in a long white dress, pale white makeup and no shoes!  Isn't it a little chilly to go barefoot in London? 

Ciara had an exciting week with the announcement of her engagement to rapper Future. But, she may have a future on the worst dressed list! The "Body Party" singer wore a sheer Alon Livne gown to the Moet Rose Lounge in Houston. She definitely has a rockin' bod, but the cutouts, patent leather detail and mega slit make it look like she's trying too hard.

Rachel Bilson is known for her casual, cool California style, but she seemed to be channeling a high-fashion prairie girl in a floor-length frock at the Chloe fashion show in L.A. The "Hart of Dixie" starlet was just too buttoned up in a white blouse and long striped skirt. Time to get back to your "O.C." roots!  

She's not the only star to get a failing fashion grade! Chloe Moretz and Dianna Agron both sported styles better suited for someone three times their age.
