One of these beautiful blondes stars on 90210. The other used to star on The Hills, and has since moved on to ... dating Chicago Bears quarterback Jay Cutler.

Both of them have us seeing red ... in a good way!

The reality star wore an Old Navy coat out and about in New York, while the actress topped a casual outfit with a red peacoat to run errands in the same city:

Who looked more ravishing in red?

Kim Kardashian is a frequent subject of our style showdowns.

Unfortunately for her, she's been absolutely trounced twice in the past week alone by Blake Lively and Nina Dobrev, respectively. We're talking routs here.

Can she rebound right here against Kristin Cavallari? Both rocked the same Hannah Marshall dress recently, although Kim also featured a belt (and booty) ...

Who looked better in this form-fitting number, the former star of The Hills or the professional celebrity? Vote away, celebrity fashion critics ...

The Hills stars Kristin Cavallari and Stephanie Pratt won't win a lot of fashion awards for these. If there even are any fashion awards. That's unclear.

In any case, where do we even begin? At the Salt premiere in Hollywood, Kristin debuted a really short dress with spiked shoulder pads. Yeah. Wow.

Stephanie, meanwhile, attended the premiere of The Extra Man in New York wearing the drapes from a house with 1970s decor. Very chic ... we guess.

Who's got the better look?

Kristin Cavallari is California cool. At least in terms of the clothes she wears. Whether she's going for casual or sexy, she always gets it just right.

As you can see, be it in a black dress, tight jeans and high heels, or shorts paired with a cute red top, KC's fashion comprises many hits and few misses.

Note that The Hills girl gives her style a tough edge with a pyramid studded Novella Royale "Mister" bag while out and about in Hollywood in each ...

What's Kristin Cavallari's best look?

Kristin Cavallari is a very cute girl. One who can be painful to watch try to read cue cards and act out fake drama on The Hills, but nevertheless, a cute girl.

She's not afraid to show off, either. Wearing a short-sleeved, see-through lace shirt over her bra to a club this weekend, she left little to the imagination.

The $5 question is whether or not that's a good thing or not.

One of our favorite things about Lauren Conrad was that she never seemed desperate for attention. Her Hills replacement? Well, the outfit speaks for itself.

You tell us in the poll below: Is it sexy or just plain skanky?

Kristin Cavallari's outfit is totally ...

After MTV plucked Kristin Cavallari out of obscurity and plunked her down in the middle of its scripted reality smash, The Hills, you knew an appearance at the network's VMAs was a foregone conclusion. As was her looking great.

Wearing essentially the same dress as Katy Perry, though? A little risky!

As you can see, Kristin Cavallari and Katy Perry were both gorgeous in their matching metallic dresses at the fake awards gala in New York City Sunday.

For Perry, known for a wild sense of style almost up there with Lady Gaga, this was rather conservative - and surprising to be in the same one as KC.

Who looked better?

Love her. Hate her. Say what you want about her.

Kristin Cavallari is coming to The Hills. And the 22-year-old is ready to shake things up as the show's new focal point, replacing the retired Lauren Conrad.

In this case, however, she's not feuding with LC, but going toe-to-toe in a fashion clash with Rihanna. The reality TV star wore a Charley 5.0 dress to dinner in W. Hollywood, while RiRi rocked the denim tube dress during a day of shopping in N.Y.C.

Who wore this dress better?

Celebrity gossip followers are accustomed to seeing Kim Kardashian nude, or at most wearing a bikini.

But in the latest issue of Oprah Winfrey's O magazine, the socialite previews this fall's hot fashion and says she doesn't mind covering up a bit, especially when the outfit fits her body shape.

“The higher neckline and longer hem are conservative, but it’s fitted to show off my curves,” she said.

Kim is joined in the feature article by Kristin Cavallari - yes, Oprah Winfrey essentially endorses the fashion views of two women that can barely read the Teleprompter on their reality shows - who agrees that classy can still equate to sensual.

“It’s sexy without being in-your-face — it has class," she said.

The Hills fans know this is not the first time Kristin Cavallari and Audrina Patridge have squared off. But this is less likely to end in cheating rumors and a screaming match, with the former declaring "you f*%ked with the wrong girl!"

No, this is merely a style showdown featuring bags.

For nights out in Hollywood, Audrina Patridge accessorizes her sexy party-girl style with a sleek patent Alexander McQueen purse. See photos below ...

Meanwhile, The Hills' contrived new Lauren Conrad stand-in, Kristin Cavallari, prefers to tote her Alexander Wang bag everywhere from Hollywood to N.Y.C:
