Fashion Face-Off

Katy Perry has been a fixture on the campaign trail, performing at President Barack Obama's rallies ... while wearing custom-made, skin-tight, form-fitting dresses.

Last night, she wore a blue one emblazoned with Obama's "Forward" campaign slogan; last week, Perry's white number became the hottest "ballot" of all time.

Which dress - by Abigail Greydanus, an L.A.-based designer - do you like better? Vote!

Not all actresses busted out on the 2012 Emmy Awards red carpet.

Some simply placed an order of legs.

During a night that celebrates fashion as much as comedy and drama, a trio of beauties stuck with the same exposed theme, one perfected by Angelina Jolie at the Oscars.

Who pulled it off better, Heidi Klum, Jena Malone or Giuliana Rancic? Decide and vote now:

The 2012 ALMA Awards - which honor outstanding Latino artistic achievements in television, film and music - were taped last night at the Pasadena Civic Auditorium.

The bad news? Viewers will need to wait until Friday (8 p.m. ET on NBC) to actually watch the ceremony.

The good news? You can ogle a bit of fashion from the festivities below, as we pit Eva Longoria against Glee actress Naya Rivera, who appears to have enjoyed a bounty-filled evening at the event.

Slushies, track suits and the most annoying music teacher ever created all return tonight, as Glee Season 4 gets underway.

Shifting the action away from Ohio, a lot of time will be spent with Rachel as a student at NYADA in New York City, tormented by a dance instructor portrayed by an awfully impressive Kate Hudson.

Both these beautiful actresses walked the red carpet of a party held in the show's honor last night, prompting this obvious THG inquiry: Who looked better at the Glee bash? Weigh in with your mouse now:

Starting tonight, Demi Lovato and Britney Spears will judge contestants on The X Factor Season 2.

But before we watch these young superstars hand out compliments and critiques, let's do a bit of both ourselves, shall we?

The singers walked the red carpet of an X Factor premiere party in Hollywood last night, with Demi donning a short black skirt and Britney feeling a lot more blue. Which pop star pulled off her outfit best? That's for us to ask - and you to decide!

Compare. Contrast. Vote now.

Selena Gomez, Vanessa Hudgens and Ashley Benson head south for Spring Breakers, an upcoming drama that finds the gals doing some dirty work for a drug dealer played by James Franco.

But before hitting the beach, the actresses spent time in Toronto over the weekend, attending a photo shoot for the film. And looking quite fashionable while doing so!

The question, of course: Which young beauty looked the most fashionable? Gomez, who also walked the red carpet for Hotel Transylvania with a couple cute dates; Hudgens; or the star of Pretty Little Liars? Vote now:

Jennifer Lawrence debuted a new, gothic look that made her nearly unrecognizable on the red carpet at the Toronto International Film Festival on Saturday.

Promoting her new film Silver Linings Playbook, The Hunger Games heroine rocked a sleek, straight new 'do, bright red lipstick and black-polished fingernails.

J-Law wore a strapless black and red Christian Dior Haute Couture gown and black Dior shoes, a somewhat severe, gothic look that was nonetheless elegant.

A fine line, for sure, but it works. How does it stack up with some of her past red carpet looks, though? That's for you to decide in the Fashion Face-Off below!

Two talented singers. Two different styles.

Before Taylor Swift's stage-diving VMA performance, she walked the red carpet in a sleek white J. Mendel pantsuit and classic red lips at the annual MTV gala.

Meanwhile, Alicia Keys rocked a one-shoulder, draped silver gown and asymmetrical 'do to boot before her collaboration with Nicki Minaj (and Gabby Douglas).

There's really no wrong answer with these two, but whose MTV Video Music Awards style do you like better? Cast your vote in THG's latest Fashion Face-Off!

It is on between Demi Lovato and Emma Watson.

Both young beauties made an appearance at the 2012 Video Music Awards, with Lovato taking home the trophy for Best Video With a Message and with Watson simply being awesome as always.

In our latest VMA-based Fashion Face-Off (we've also pitted Drake against Chris Brown and Katy Perry against Rihanna), we take Demi and her short black dress and we ask viewers to decide if that's preferable to Watson's multi-colored skirt.

Which do you like best?

Chris Brown and Drake were both among the MTV VMA winners last night. Better yet, no bottles were thrown or blows were exchanged to our knowledge!

Drizzy won Hest Hip-Hop Video for "HYFR," while Breezy took home the prized Best Male Video honors with his self-directed smash hit "Turn Up The Music."

Dude even got a hug and kiss from Rihanna to boot. Point ... Chris?

A question for another time. The question for right now is which of these sharp-dressed music hunks looked the best on the industry's wildest night.
