JENNIFER ANISTON

We're celebrating today in the PEOPLE.com offices. Why? It's Friday, and Jen is finally wearing a color other than black! She poses in an eggplant strapless design by Burberry (and coordinating Casadei heels) at the premiere of her new flick We're the Millers in N.Y.C.

DIANE KRUGER

Leave it to the fashion risk-taker to choose a bold mix of prints via this strapless Mary Katrantzou dress, complete with an asymmetrical hemline. She teams the dress with an Edie Parker clutch and Stuart Weitzman heels at the Fox All-Star party in West Hollywood.

EMMA ROBERTS

Taking a page from her co-star's usual style playbook, the actress wears a black Michael Kors look with a high-low hemline and adds a pair of Chopard diamond globe earrings at the premiere of We're the Millers in N.Y.C.

LUCY HALE

We wish we could borrow the The Pretty Little Liars star's black-and-white Joy Cioci crochet mini for our friend's wedding this weekend. She adds an extra hit of chic to the look with a gold-embellished Peggy Hartanto belt at the Young Hollywood Awards in Santa Monica, Calif.

ZOOEY DESCHANEL

The actress continues to ride the tights train (despite, you know, the 80 degree weather), pairing her trusty opaques with a tea-length black Preen dress, turquoise Chanel bag and matching pendant at the Fox All-Star Party in West Hollywood.

ALYSSA MILANO

Keeping Hollywood's high-fashion jumpsuit trend alive, Alyssa selects a long-sleeve Stella McCartney onesie with a slashed bodice at the Young Hollywood Awards in Santa Monica, Calif. And the bold fashion choices keep on coming with her highlighter-yellow Marissa Webb pumps.

DEMI LOVATO

We were so distracted by the X Factor judge's gorgeous blonde blowout that it took us a few minutes to notice the rest of her ensemble: Black leather pants, coordinating blazer and a trio of funky necklaces at the Fox All-Star Party in West Hollywood.

KELLY ROWLAND

Yes, body-con has been in the singer's fashion wheelhouse since her Destiny's Child days. But thanks to the futuristic print on this blue-and-white mini (worn to the Fox All-Star Party in West Hollywood) the style feels totally fresh.

KELLY OSBOURNE

With all the black on the carpet lately, we commend the newly-engaged star for stepping out in this canary yellow fit-and-flare dress, accessorized with her signature lavender beehive, Lana Jewelry danglers and that sparkly new bling on her left hand at the Young Hollywood Awards in Santa Monica, Calif.

MINKA KELLY

When you're rocking a dress like Minka's allover-printed Monique Lhuillier number, you don't need to add any bells and whistles. The actress keeps it simple, letting the dress (and those bombshell waves) take center stage at the Fox All-Star Party in West Hollywood.

KATE HUDSON

We can see your weave. We're talking, obviously, about the basket weave design on Kate's denim Balmain mini, which also features floral and chain-like embellishments, chosen for the Hollywood premiere of Clear History.

KELLY OSBOURNE

Her lace-sleeved dress is so flattering and her lavender updo looks perfectly undone, but what we really want to talk about is the animated Hèrmes bag Kelly is carrying, which she revealed she bought for her mum in Paris years ago and finally broke out for the Do Something Awards in Hollywood.

JENNIFER HUDSON

She can hit those high notes and she can rock those high-waisted shorts. The singer wears them to the Do Something Awards in Hollywood with top-to-bottom Versace: a printed button-down and an explosion of bold accessories including white ankle-strap pumps and a golden necklace that just can't be ignored.

SOPHIA BUSH

She deemed the Do Something Awards (which she hosted) the "best night ever" and we have a feeling it has something to do with the fact that Sophia chose this plunging teal-and-white Monique Lhuillier stunner, accessorized with a killer tan and perfect waves, for the Hollywood event.

CARMEN ELECTRA

The silhouette, shade and sheen of her dress are so bridesmaid, but the dramatic train and curve-hugging fit are so scene-stealer. Carmen tops off the gown with a sleek and super-long pony and heavy eye makeup for the Do Something Awards in Hollywood.

ANNA GUNN

All will be revealed in Breaking Bad's final season, and at the N.Y.C. party to celebrate the premiere, one of the hit show's stars reveals quite a bit herself. Mrs. Walter White sports a plunging LBD with, why yes, that's a sheer cowl neck.

HEIDI KLUM

As if the supermodel's black-and-yellow Michael Kors midi didn't have enough personality with that allover leaf print, she adds a spotted belt and dramatic danglers to the strapless number at an America's Got Talent pre-show event in N.Y.C.

LILY COLLINS

At first glance, the actress looks like she's wearing a summery dress. But she's edgier than that! It's actually a matching floral top and skirt by Sachin + Babi. She ditches sandals for fall-ready black Casadei pumps with gold detailing at a promotional event for The Mortal Instruments: City of Bones in Miami.

KATE UPTON

The face of David Yurman's latest campaign shows off that gorgeous face (and other assets) in a one-shoulder LBD, a bold red lip and bombshell waves at the jewelry designer's private party in N.Y.C.

AMANDA SEYFRIED

Once you stop obsessing over her perfect ringlets, take a moment to reflect on Amanda's strapless Givenchy by Riccardo Tisci dress featuring a fitted bodice and ruffled skirt, worn to a Lovelace screening in N.Y.C.

ROSE BYRNE

If this looks familiar, that's because Gwyneth Paltrow rocked the same print earlier this year. Rose breathes new life into the Erdem pattern by picking a sheer-paneled dress and adding metallic Jimmy Choo pumps at an N.Y.C. screening of I Give It a Year.

SHAILENE WOODLEY

We used to hang dream catchers in our bedrooms, but Shailene hangs one around her neck. The actress pairs the statement necklace (dreamy or nightmarish?) with a turtleneck crop top and a calf-length skirt (both Proenza Schouler) for the screening of The Spectacular Now in L.A.

SHARON STONE

The 55-year-old star must be drinking from the fountain of youth, because she is killing it in this gold-studded LWD with a slash at the décolletage, selected for the Lovelace screening in N.Y.C.

KARLIE KLOSS

This is who bandage dresses were made for. The tall, lean, beautiful supermodel (is that redundant?) stuns in a raspberry halter with a sexy keyhole cutout at the Victoria's Secret Body by Victoria event in N.Y.C.

BEHATI PRINSLOO

Yep, bandage dresses were made for her too. Wearing the universal uniform of supermodels, the newly-engaged star also chooses a skintight dress in a summery watermelon shade for the Victoria's Secret Body by Victoria event in N.Y.C.

SIENNA MILLER

Judging by the rose garden growing on her Dolce & Gabbana fit-and-flare dress, the actress has a green thumb when it comes to style. She finishes the look with unique strappy sandals, a pink lip and shoulder-grazing danglers at the BMW i3 Reveal Party in London.

ANGELINA JOLIE

Sticking to one of her favorite labels and her favorite color by far, Angie shows up in a one-shoulder Saint Laurent gown with a sophisticated silhouette for the premiere of World War Z in Tokyo.

RACHEL BILSON

The Hart of Dixie star sure loves an embellished mini. Rachel shines in an allover sequin 3.1 Phillip Lim number, accessorized with metallic Brian Atwood pumps at the CW, CBS and Showtime Summer TCA party in L.A.

SARAH MICHELLE GELLAR

It may be the middle of summer, but SMG doesn't seem to notice. She pairs her Izmaylova LLBD (leather little black dress) with dramatic studded Jimmy Choo pumps and a bordeaux pout at the CW, CBS and Showtime Summer TCA party in L.A.

PAULA PATTON

Giving the dancers in her husband's music video a run for their money, the actress rocks a low neckline and a thigh-high front slit simultaneously via a racy black-and-white Basil Soda gown, plus coordinating pumps at the 2 Guns premiere in N.Y.C.

TYRA BANKS

Another star putting it all on display, the model strikes a fierce pose in her plunging, second-skin lace dress, made even sexier thanks to her side-swept curls at the CW, CBS and Showtime Summer TCA party in L.A.

ANNA FARIS

It makes sense that someone who lights up the big screen also lights up the red carpet. The actress is all sunshine and smiles in a canary-yellow midi (featuring a metallic stripe down the middle that matches her Jimmy Choo sandals) at the CW, CBS and Showtime Summer TCA party in L.A.

KATY PERRY

Cleary Katy knows shades of this cool color are hot right now. The singer selects a cobalt Tadashi Shoji dress featuring floral appliqués and leather, accessorized with coordinating Pedro García shoes at the premiere of The Smurfs 2 in Westwood, Calif.

BRITNEY SPEARS

Also showing her love for blue (really, what else can you wear to The Smurfs 2 premiere?), the Hollywood mom puts her curves on display in one of those sexy bandage dresses she loves so much at the Westwood, Calif., event.

CAMERON DIAZ

No color, minimal accessories and almost zero makeup. But all of the above aren't necessary when you're wearing the perfect fit-and-flare LWD, as Cameron is at the Baby Buggy Summer Dinner event in East Hampton, N.Y.

NINA DOBREV

The oversize gold safety pins on Nina's red Versus Versace mini are giving us flashbacks to this year's punk-themed Met Gala. The Vampire Diaries star adds metallic Christian Louboutin pumps (another trend on the rise right now) and an Amanda Pearl clutch at the Variety Power of Youth event in Universal City, Calif.

NAOMI WATTS

Did the invitation to the Baby Buggy Summer Dinner in East Hampton, N.Y., read, Minimal makeup only? Naomi follows Cameron's lead and goes for a simple ensemble devoid of color and hardly a stitch of makeup. But who's looking at anything besides those Roger Vivier mega-platforms anyway?!

ZOË SALDANA

The actress racks up style points in a red-and-white Antonio Berardi dress with quite the flouncy hemline at the Audi International Polo event in Windsor, U.K.

ANNA KENDRICK

There's matchy-matchy and then there's matchy-matchy-matchy. The actress goes for the latter in an embellished off-white Temperley London mini, plus satiny heels and a shiny Jimmy Choo clutch in the same shade, at the Dizzy Feet Foundation's Celebration of Dance Gala in L.A.

CHRISTINA APPLEGATE

Is it awards season already? Nope, it's just Christina having a very glam moment in a stunning lace Zac Posen gown with a hint of metallic (not to mention that shiny Oroton clutch!) at the Dizzy Feet Foundation's Celebration of Dance Gala in L.A.

ASHLEY GREENE

A cable-knit sweater...in July? We're breaking a sweat just looking at Ashley in her chunky Isabel Marant top, paired with denim shorts and black Matt Bernson peep-toe booties at a private pre-show event for the Bruno Mars and Ellie Goulding concert in L.A.

CHRISTINA AGUILERA

Another pop star who loves her crazy-tight minis. The singer shows off her slimmed-down figure (and whiplash-inducing décolletage) in a Pepto-pink Alaïa mini at NBC's Summer TCA Tour event in Beverly Hills.

ASHLEY TISDALE

Why is Ashley standing on a red carpet and not posing on a rock in the ocean singing? She wears a Bless’ed Are The Meek dress seemingly inspired by Ariel's signature shell bra at the Hub Network's Summer TCA Party in Universal City, Calif.
