Last night, Paris Hilton took over the rooftop at the Thompson Beverly Hills hotel to launch her latest beauty products, the Celebrity Styler ($64.99) and the Ultimate Brush ($9.99). Everything was pink: the lighting, the spicy tuna rolls, the heiress' dress and, of course, the new styling tools.

The hair-and-beauty collection was designed for the girl-on-the-go. The brush promises quick drying time, while the iron/curler lets you switch up hairstyles in a heartbeat, going from pretty Paris waves to pin-straight Nicky Hilton locks.

Speaking of Nicky, she was right on trend in a striped dress, supporting her sis alongside parents Kathy and Rick, Aunt Kyle Richards and Doug Reinhardt. Also at the bash were Paris' former BFFs from her reality series (guess she didn't really mean TTYN!). While some kept it simple in cute LBDs, others pranced around in ridiculously short skirts and enough embellishment to decorate the Rockefeller Center Christmas tree.

And there was almost as much fur as there was bling. When she wasn't posing for pics, Paris stayed warm in a light gray vest, while other guests went for cropped jackets like this Fabulous Fur one.

Meanwhile, across the country, another star was showing off her love for animal skin with the new Jimmy Choo for H&M zebra clutch. Find out who in mystyle's Soiree Style gallery.

The '80s have been back for a while now, so seeing blue eye shadow on the red carpet is no surprise. In fact, the color is one of the hottest makeup trends for winter.

But blue eye shadow and a cobalt dress? That can be a little much.

At an awards gala last night, Eva Longoria Parker took inspiration from her Ina Soltani dress and went overboard with a lighter shade of blue on her lids. At least Kate Walsh broke up the Smurf palette with a bold lip during her Letterman appearance a couple days before.

Kelly Osbourne and her fiancé, Luke Worrall, have only been together for a year and a half, but already they're starting to look like each other! Just check them out at h.wood last night, where they celebrated Kelly's 25th birthday, which is actually today. (Happy birthday, Kelly!) We normally don't like it when folks do the matchy-matchy thing—puke!—but we think the couple's similar peroxide-blond haircuts are cute. We also like how Kelly's dotted dress complements Luke's striped sweater. These lovebirds are officially on our list of fashionable It couples to watch!

PERP: Jaime King

SCENE OF THE CRIME: Spike TV's Scream 2009 Awards

VERDICT: Vote haute or not in the Fashion DUI gallery!

Here's what caught our eye on the Web this week:

It's Pumpkin Pickin' Time for tots and stylish celebs alike. How Kristin Chenoweth hailed a cab while balancing her big orange purchase in those heels is beyond us! (E! Online)

Kristen Stewart is worried about being too skinny. Maybe she should give Ralph Lauren a call to ease her mind. (Huffington Post)

Even celebrities who get paid for just being themselves have their bad fashion days. And Lo Bosworth isn't afraid to admit it! (Twitter)

Selena Gomez is the latest celeb to get her own clothing line. It's going to be "pretty, feminine and bohemian"—and we're guessing way cuter than her pal Taylor Swift's boring sundresses. (Style Crunch)

A black Disney princess is finally born. Now we can all live happily ever after. (Spoiled Pretty)

Sarah Jessica Parker says, "Take Me, Pull Me, Desire Me, Love Me" with her stilettos on the set of Sex and the City. What ever happened to good ol' satin Manolos? (Red Carpet Fashion Awards)

Speaking of Sex and the City, Jason Lewis gets in the sheets with Charisma. We know we'd buy the linens if they came with Smith Jerrod! (NY Daily News)

And Tyra Banks goes wild with curls. Here's how you can get her look! (Limelife)

Even funny gals like Tina Fey like to get dolled up now and then.

The 30 Rock star visited The Late Show with David Letterman last night and dished all about going glam for next month's Harper's Bazaar.

"They put these long, long hair extensions, that's mostly wig, on me," she said of her cover shoot. "And when they put all the fans on you, the wind machine, the lights and all the gay magic you start thinking like, 'Yeah, I look like this!"

Of course, when the wind stopped, Tina said she returned to her normal "homely" self. But we think she looks pretty fab without the "gay magic." And right on trend, too!

Keep reading to see the comedienne's au courant polka-dot ensemble—and to hear the virginity hilarity that made us forget all about Letterman's sex scandal.

What's the key to adapting a look from another decade? I'm interested in trying out the '40s trend that I'm seeing everywhere.
—Alice K., Portsmouth, Virginia

Let's not stop there. I have the key to adapting any look, from steampunk to early Cyndi Lauper, for the new millennium! Think of the three biggest standout attributes of a certain era. For example, with the early to mid 1980s, it was about heavily layered, rubber accessories; big, frizzy, often sculpted-looking hair; and massive shoulder pads. For the 1940s, it was about exaggerated, swooping hairdos (curlers required); hard, defined, red lips; and—well, massive shoulder pads.

When you're ready to adapt the look to this era, choose no more than two of those aspects. One is even safer.

Zona's botanical-enriched skincare line promises a spa-like experience from the comfort of your own home. For our most recent R&R session, we tried the Face & Body Cleanse Soap ($10), Face Cleanse Sponge ($10) and Body Cleanse Sponge ($12). Keep reading to see what we thought of them.

Pros: The soap lathered well on the two sponges, which were great exfoliators, and gave a deep clean.
Cons: The soap didn't rinse off well.
—Kristen H., Development

True Blood star Anna Paquin gave us a peek at her personal style during LA Dogworks and Good Dog Animal Rescue's "A Night of Emotion"...

What She's Stylin': I think the dress is Tracy Reese. The tag is no longer inside. It's been in my closet forever. I like it! My shoes are by Jimmy Choo.

Fashion Philosophy: I mostly wear jeans, T-shirts, summer dresses, shorts and sandals. If I'm going out, I like to dress up.

Genius in a Bottle: I just started using Moroccan Oil's shampoo and conditioner. It's great for girls who dye their hair blond, like me. It actually makes your hair not look like it got sucked down a drain and then slapped on your head. It's nice!

Color Crave: I like a lot of black. The teenage goth girl in me is still peeking out every once in a while, but I'm branching out. I'm wearing navy blue tonight.

Earlier this week, Khloé Kardashian was spotted in Beverly Hills registering for gifts immediately following her E! Emmys Fashion Police hosting gig. You gotta do what you gotta do when you're planning a quickie wedding that's set to take place this Sunday. Just sayin'! At least the reality star, who wore an über-sexy Alexander Wang LBD and to-die-for Louboutin lace booties for the excursion (monogrammed glasses, anyone?), doesn't have to squeeze extra workouts into her tight schedule. She's in the best shape of her life!

We caught up with actress Regina King (seen here at Fashion Week last spring) to get the dish on her personal style...

Denim Diva: I'm a jeans girl. I probably have about 40 pairs of jeans. I love J Brand and Lucky. Also, there's a little el cheapo store by my house that I like. It sells jeans for $29.99—you just have to try them 'cause even if you wear a size 4, they might be fitting like a 1!

Designer Shout-Out: I wish Richard Tyler was still designing. I have a bit of a butt and no hips. His stuff creates hips for me. His dresses fit me so perfectly that I'm forced into buying vintage Richard Tyler.

Fitness Fab: I just started this new class at Equinox in West Hollywood that Reebok and Cirque du Soleil did called Jukari. You're on the trapeze and it really works your core. It looks graceful, but it's hard to do!

Beauty Splurge: I spend way too much money on lip gloss, which shouldn't cost more than $5. Fresh, which is about 20 bucks, is my absolute favorite. I have their lip gloss all over the house, in every drawer!

Back in April, 75 percent of you said Kim Kardashian shouldn't dye her naturally shiny raven locks blond. We felt the same way. Well, she did—and even we had to admit that she didn't look that bad. Still, we breathed a sigh of relief when Kimmie took to the streets of Beverly Hills yesterday afternoon showing off freshly darkened hair. The reality star's summer fling with lighter tresses has ended! Are you happy the brunette vixen is back? Sound off below!
