WTF Are They Wearing

Kristen Stewart was lacy and racy in the see-through black jumpsuit she donned for the Zuhair Murad fashion show at Paris Fashion Week on Thursday (July 4). While many fashion bloggers marveled at the romper, calling it "stunning," we're gonna have to disagree. The outfit makes her butt look big, and what's with the granny panties? Plus the pseudo cornrows do nothing for her.

We're used to Rihanna going topless all over Instagram, but her sheer Chanel shirtdress, worn to the house's show during Paris Fashion Week, was the equivalent of her online photo exploits. In other words, despite the classy label, it was a tad too tacky and trashy, two "T" words that you don't want associated with you during the fashion industry's biggest time of the year.

Jennifer Lawrence usually bats .1000 on the red carpet and at big events, but the Oscar winner whiffed mightily with this outfit -- simply because the pants have such a split fashion personality.

Miley Cyrus attended an L.A. launch party for the revamped Myspace on June 12, and the only thing more questionable than a return to prominence for the once mighty but now-lagging social media site was her outfit.

Gwyneth Paltrow followed her PEOPLE's Most Beautiful cover nod with a not-so-beautiful, see-through Antonio Berardi dress at the Hollywood premiere of 'Iron Man 3' on April 24. The gown's only redeeming quality is that it was sexy in the spots where the sheer panels showed off Gwynnie's toned legs and stripper's backside. We think she even went commando. Other than that? What a mess. This is som

Matthew McConaughey looks like he's trying out for the role of The Joker in his iridescent maroon and blue suit that can only be described as absolutely hideous. The actor is genetically blessed and this suit certainly detracts from that. To borrow a phrase from Annette Bening in 'American Beauty' -- is he tryingto look unattractive?

By nature, a pool party is casual and fun. It usually means bathing suits, loose cover-ups, sandals and lots and lots of sun-kissed skin -- all of which is supposed to be sexy. But Rumer Willis, the eldest spawn of Demi Moore and Bruce Willis, missed that whole "be sexy" memo when she appeared at the Marquee Pool Party in Las Vegas to celebrate the opening of the Marquee Dayclub on Apri

There are certain occasions in life where a simple black suit will suffice. A funeral. A job interview. A court appearance. But if you're Lindsay Lohan and you're headed before a judge for the bazillionth time, you don't keep it modest, prim or proper. You wear a white pantsuit comprised with possibly sheer fabric and a skirt over the pants part. Maybe?

Kim Kardashian has made sure that the whole world know she's pregnant with her first child, but she seems to be doing everything she can to conceal her baby bump. Or emphasize it before it's really even there. Hard to tell sometimes. The celebutante, who recently snagged former Lady Gaga stylist Nicola Formichetti as her very own "baby bump stylist," turned up at the opening of U.K. reta

Beyonce's baby sister Solange looked like she forgot something when she walked out the door to attend the premiere of Bey's 'Life Is But a Dream' doc in NYC last night (Feb. 12). Keys? Nope. Smartphone? Negative. Lip gloss? Got it. As you can see, Solange, who upstaged her sister in an emerald green gown at the Grammys earlier this week, forgot her pants.

Julianne Hough has had a string of hits on red carpets lately, namely at the Golden Globes and the People's Choice Awards last month -- so we were flabbergasted when she turned up in a skirt and pants at the New York City premiere of her new film 'Safe Haven' last night (Feb. 11).

Sarah Jessica Parker is the toast of the fashion world and one of its irrefutable darlings, thanks to all those years she spent prancing around in priceless couture as Carrie Bradshaw on 'Sex and the City.' She pretty much took Blahnik and Louboutin, which were already ingrained in fashion lexicon, and turned them into household names. But every now and then, even she has a red carpet clunker --

For a woman who's usually polished on the red carpet -- whether or not we personally like her attire choices -- and who just announced that she's knocked up, Kim Kardashian rang in 2013 looking like a rather inappropriate mess.

Kristen Stewart flew from Los Angeles to New York City to take part in the 12-12-12 Hurricane Sandy Benefit show -- and she looked every bit the worse for wear.

Another 'Les Miserables' premiere, another hideous dress worn by the film's star Anne Hathaway. The actress followed up the white, beaded nightmare from Givenchy she wore at the London premiere with a black taffeta dress - supposedly by Tom Ford - at the NYC premiere on Dec. 10. Congratulations, Anne. You're now the first two-time inductee into the WTF Hall of Fame.

The Givenchy gown that Anne Hathaway wore to the London premiere of 'Les Miserables' on Dec. 5 was ... well, pretty miserable.

One might think that freeing herself from the clutches of Tom Cruise and Scientology would send Katie Holmes -- who has her own clothing line called Holmes & Yang -- into a fashion frenzy, showing off her model-like height and trim body, as well as her brunette-next-door cuteness. Eh, not so much.

We're not WTF'ing over the strange cut-outs on the white dress celebutante Kim Kardashian wore to a Millions of Milkshakes opening in Kuwait. She's definitely worn stranger things. We're WTF'ing over her decision to wear this outfit in the Middle East.

Fergie of the Black Eyed Peas attended the W LOVE Hangover Ball on Nov. 28 -- but her outfit made it seem like she'd had a big evening the night before and was hung over herself when she got dressed.

At her Pink Friday fragrance launch in Sydney, Australia on Nov. 29, Nicki Minaj looked a bit like Little Bo Peep -- after a long, strange acid trip.
