This week's best-dressed list was filled with stars in perfectly fitted minimalist looks. Allison Williams stood out in a simple black halter dress, while Carey Mulligan proved that you can look fabulous in yellow.

Meanwhile, Sandra Bullock continued to hit it out of the park in an incredibly sexy lace dress (this lady is one to watch), and Rooney Mara proved that she is still one of Hollywood's best-dressed celebs.

Check out our picks for best-dressed and let us what you think.

Allison Williams In Dior


Now this is a dress! What makes this gown so special is the silhouette. The halter neckline shows off William's toned arms and creates simple, clean lines which make the actress appear taller than she is.

Carey Mulligan In Dior


Yellow can be a tricky hue to wear given not all shades of the color are very flattering. But Mulligan seems to have nailed it with this strapless dress. The boning towards the top helps to give her a nice hourglass shape, while her pink lipstick and black pumps compliment the delicate look.

Michelle Pfeiffer In Alexander McQueen


Clearly, Pfeiffer knows how to put together a balanced outfit. The strong shoulder pads on her blazer are nicely countered by her fitted white dress shirt and slightly flared pants. (Not to mention the fact that her legs look about 12 feet long).

Freida Pinto In Burberry


Pinto understands how to wear a statement piece. The actress' metallic jacquard pencil skirt is the standout garment in her outfit, so she kept the rest of her look simple, allowing us to be wowed, once again, by her fashion-forward ways.

Rumer Willis


We were happily suprised to see Willis on the best-dressed list this week. We think the young star has finally learned that less is more. This classic black dress, with a slight slit and a deep-V, is showing off all her best assets.

Jennifer Hudson In Donna Karan


Ruching and wrapping are always figure-flattering, so Hudson was smart to pick this style of dress. The singer's strappy sandals further elongate her legs, while her sexy cat-eye makeup amps up the sex appeal. A+, Hudson.

Queen Maxima Of The Netherlands


Who says royalty can't be fashion-forward? We love how Queen Maxima elevated her simple grey dress with bold accessories. Her oversized hat, metallic clutch and gold hoop earrings ensure that she is best-dressed material.

Rooney Mara In Proenza Schouler


The queen of minimalism is finally wearing color (alright, a little bit of color). This dress looks fabulous on Mara because it's refined yet of the moment. The leather top, combined with the tummy cut-out and pleated metallic strips, stay true to the actress' avant-garde style, but are still slightly unexpected.

Li Bingbing In Elie Saab


Now this is show-stopping gown! The Chinese actress may be wearing a revealing dress, but the high neckline, delicate beading and long hemline ensure that it reads very classy.

Sandra Bullock In Stella McCartney


Bullock is on fire in the fashion department lately, and this dress is no exception. The long sleeves on her black lace dress are balanced out nicely by the frock's short hemline, while her deep red lips and tousled locks make the entire look totally effortless.

More celebs who made the best-dressed list:

  • Michelle Obama in Marchesa

    This dress left us awestruck. The emerald off-the-shoulder gown highlights her famous guns, while her delicate diamond necklace draws the attention towards her voluminous locks and flawless complexion.

  • Blake Lively in Marchesa

    Lively looks like a blonde bombshell in this ensemble. Her flapper-style dress hugs her curves, and her retro waves and bold red lipstick make the look very old Hollywood.

  • Amy Adams in Altuzarra

    It's hard to go wrong in an LBD. This one is special because of the lace detailing around the neckline and the long sleeves -- few people opt to cover their arms on the red carpet, but it can actually make a dress very sexy.

  • Zoe Saldana in Sachin + Babi

    Though this ensemble has a lot going on, it works because Saldana stuck to a neutral color palette. The various dots and stripes work together harmoniously and make the actress look fashion-forward.

  • Jessica Biel In Giambattista Valli

    Biel's all black outfit is so special because of the various textures in her outfit, her patterned pumps and that pink lipstick.

  • Lupita Nyong'o in Elie Saab

    This simple red dress is perfection on Nyong'o. The color really pops against her skin tone, and the added sparkle keeps the look interesting.

  • Naya Rivera

    Sometimes all you need is a tight, long-sleeve black top (just ask Audrey Hepburn). The laid-back nature of her shirt, paired with her grey peplum pencil skirt and strappy heels, is the perfect mix of casual and sexy.

  • Rooney Mara in Lanvin

    There is a reason that Mara always sticks to neutral colors -- they look amazing on her. This white gown is very classic, but has a beautiful sculptural shoulder piece, which is the type of fashion risk-taking that Mara has become known for.

  • Lily Collins

    'Tis the season for sparkle. Collins' little shift dress is adorable on her, especially when paired with thigh-high boots, tousled waves and deep red lipstick.

  • Reese Witherspoon in DVF

    This gray dress fits Witherspoon like a glove, and the black lace detailing around the edges is very slimming.

  • Deepika Padukone in Gauri and Nainika

    Mustard yellow is a tricky shade to pull off, especially when worn head-to-toe, but Padukone managed to make it work since she has the perfect coloring for the hue. The dress itself is very classic and when paired with pulled back hair and chandelier earrings, it makes for one glamorous look.

  • Evangeline Lilly in Catherine Deane

    We're not sure whether it's the embroidered top, the flowing skirt or her effortless braid, but there is something about this ensemble that is so mesmerizing,

  • Alexa Chung

    This is a perfect outfit. The oversized, menswear-inspired coat is a great compliment to her feminine, little white dress, while the red lipstick adds just the right amount of sex appeal. Her tousled waves, graphic clutch and platforms round out the look, making the style icon look fashion-forward yet effortless.

  • Rashida Jones in Proenza Schouler

    Though Jones' oversized black dress could have easily skewed sloppy, the deep-V alludes to her slim figure, while her black bralette poking out ensured that she looked sexy.

  • Lea Michele in Dolce & Gabbana

    Lea Michele sure did shine in this dress. Not only is red a great color choice for the season, but the tiny, expertly placed embellishments made sure she was the center of attention.

  • Naomi Campbell in Zac Posen

    This rich burgundy gown looks amazing on Campbell. Not only does the shade work well with her complexion, but the silhouette compliments her long, lean frame.

  • Lily Donaldson in Marc Jacobs

    Donaldson has managed to look demure in a completely sheer gown. Though her dress is revealing, the long sleeves and hemline, combined with the print, keep our attention on the dress and not what's underneath.

  • Lindsay Ellingson in Sophie Theallet

    Aah, minimalism at its best. The blue-grey dress is so simple, yet the fit is spot on, which makes it extremely flattering. The Victoria's Secret model went with barely-there makeup and side-swept, straight hair which made the entire ensemble look very clean and elegant.

  • Angie Harmon in Angel Sanchez

    The "Rizzoli & Isles" actress achieved perfect balance with this gown. The voluminous top works so well because it is offset by the textured, slim white skirt, while her sleek updo is ideal for the strapless neckline.

  • Princess Charlene of Monaco

    Velvet dresses aren't just for the holiday season anymore. Though many people are scared of the fabric because it can easily look outdated, if it's worn in a modern silhouette (and with a fierce red lip), it can be lovely.

  • Jennifer Lawrence in Christian Dior

    The "Hunger Games" heroine's press tour has been rough (there have been a few worst-dressed moments), but she seems to have found her footing in this vanilla-colored strapless gown with a crystal embellishment. It's refined yet beautiful, and the slightly higher hemline in the front of the dress allows us to see her delicate strappy shoes. This is also the best neckline to show off her new short 'do.

  • Amy Adams in Vivienne Westwood

    Sometimes less is more, as proven by Adams. The dress itself is rather simple, but the grape color really pops against her fair skin and makes this a standout look.

  • Eva Longoria in Victoria Beckham

    Longoria's dress is a very wearable take on the popular lingerie trend. The lacey straps on her gown are a subtle nod to the fad, but the actress kept the rest of her look classic, making this an ensemble that can stand the test of time.

  • Kiernan Shipka in Miu Miu

    The 14-year-old "Mad Men" star looked cute and age-appropriate in this matching top and skirt combo. But what really put this ensemble over the top was her tri-colored pumps.

  • Naomie Harris in Burberry

    Long, clean lines are what make this outfit so successful. Harris' pin straight hair and floor-length gown are making her look 10 feet tall.

  • Julia Louis-Dreyfus in David Meister

    This body skimming black dress is a great silhouette for the "Veep" star. It is hugging her in all the right places, while the keyhole embellishment is adding just the perfect amount of bling to her otherwise neutral look.

  • Elizabeth Banks in Alexander McQueen

    Wearing feathers on the red carpet is often a challenge, as they can easily come off as costumey. But here, the "Catching Fire" star paired them with an elegant, long navy dress featuring a sleek halter neckline, which balanced out the playful plumage.

  • Michelle Jenner in Christian Dior

    This jewel-encrusted white dress is a real show-stopper. The interesting neckline is a nice departure from what we usually see on the red carpet, and her graphic pumps kick the look up a notch.

  • Zoe Saldana in Calvin Klein

    Saldana's dress may have been simple and clean, but it definitely wasn't boring. The grid pattern on the dress added a bit of visual interest, while her gold belt, red lipstick and sparkly pumps took the look from ordinary to extraordinary.

  • Lily Collins in Givenchy

    It's not news that slip dresses are having a moment right now, but the challenge is making them look appropriate for the outside world (and not like lingerie that wandered out of the bedroom). Here, Collins opted for a red silk dress with lace detailing, and she made the outfit very glamorous with red lipstick and intricate pumps.

  • Allison Williams in Misha Nonoo

    This outfit is spectacular on every level. First of all, the oversized button-up shirt paired with that black silk faille dirndl skirt is genius -- so simple, yet so elegant. And her beauty look is spot on, too. Her slicked-back hair and red lipstick are the perfect compliment to her effortless ensemble.

  • Jessica Biel in Christian Dior

    This is a great LBD with a twist. The yellow embroidery and white and lilac panels made this a nice dress to transition into cooler weather. We also love that she matched the yellow detail in her shoes to her outfit.

  • Natalie Portman in Christian Dior

    When you wear a jumpsuit, the fit needs to be perfect. And here, Portman made it clear that this one was tailored to fit her body exactly. The fold-over top gives the look dimension, while the bodice fits right against her ribcage, showcasing her curves.

  • Rita Ora in Calvin Klein

    We couldn't be more pleased to see Rita Ora on the best-dressed list this week -- it's about time. The singer finally pared back her look and went with a classic, long black dress, simple makeup and sultry waves. This is the Rita Ora we want to see more of.

  • Rose Byrne in Jonathan Saunders

    This dress is so simple, yet so beautiful. The Australian actress found a great color and silhouette for her body.

  • Naomie Harris in Vivienne Westwood Gold Label

    A print on the red carpet can be tricky to pull off if it's not the right color or the right size. But this graphic black and white pattern is doing wonders for the actress. The cut of the dress, the off-the-shoulder neckline and the darting is extremely figure-flattering, and her choice of turquoise pumps makes the outfit that much more exciting.

  • Kiernan Shipka in Preen

    Seriously, how is the "Mad Men" star only 14 years old? She always kills it on the red carpet, and this white look is no exception. The asymmetrical hemline is a nice detail, while the geometric print on her shirt keeps her ensemble age appropriate.

  • Poppy Delevingne

    We'll admit that Poppy's dress is a little summery for this time of year, but the photo was taken in Los Angeles, so we'll give her a pass. The cut of this frock is what makes it so successful. It is fitted up top and flares out to a midi-length that is so flattering on the tall socialite. We are also in love with her Valentino ankle booties.

  • Jessica Biel in Chanel

    We love the simplicity of Biel's white strapless gown and how her neckpiece is so elegantly draped over her shoulders. This look is just fashion-forward enough without being too much. It looks like Mrs. Justin Timberlake doesn't just have good taste in men.

  • Kate Hudson in Gucci

    There are so many things that are right with this gown. The plunging neckline works so well on Hudson, especially when paired with a more demure skirt. She looks refined and sexy, all at once.

  • Kat Dennings in Naeem Khan

    This dress is amazing on Dennings. The color, pattern and cut all work together to make her look fabulous. Her choice of pumps is also spot-on, as their nude color is making her legs look longer.

  • Poppy Delevingne in J'Aton Couture

    If you ignore the crown (in her defense, she was at a derby), her dress is actually quite pretty. The lace detailing and tiering at the bottom are very delicate and make this a stunning ensemble.

  • Jennifer Garner in Max Mara

    We know, we know, it's after Labor Day, but something that looks this good can't possibly be wrong. While the color choice may not be ideal for November, the cut and fit are. We are obsessed with Garner's minimal jewelry and sleek updo. She deserves an A+.

  • Li Bingbing in Elie Saab

    There is perfect balance in this look, and that's why it works so well. Though the actress went with wide sleeves, they don't overwhelm the ensemble because of the short hemline. We also love how she has injected a little personality into the outfit by wearing red heels and red lipstick.

  • Kate Beckinsale in Gucci

    This pale blue hue is heavenly on the brunette actress. The strapless dress with the nipped-in waist highlights all her best assets, and her side-swept locks help to draw attention towards her bold brows and minimal makeup.

  • Taylor Swift in Elie Saab

    Now this is a dress. Red looks great on Swift (no wonder that's the title of her latest album), and the embellishments and long train on the gown are just enough drama for the red carpet.

  • Jana Kramer in Theia

    The country music singer hit it out of the park with this outfit. The combination of the full, printed skirt with the long-sleeved black top is so laid back, yet so effortlessly chic. It is very reminiscent of Audrey Hepburn.

  • Kelly Rowland

    A LBD is a classic, but we love how this particular one has a plunging back. It keeps us on our toes and makes things interesting.

  • Natalie Portman in Dior

    So simple, yet so elegant. The princess-style dress looks gorgeous on the "Thor" star. Portman is the picture of Hollywood glamour.

  • Blake Lively in Balmain

    It's rare that we see off-the-shoulder done so well on the red carpet. Lively's bouclé houndstooth dress looks stunning against her complexion. The sparkly, gold-accented is fashion-forward, while the flouncy skirt helps to keep the look young and fun. Clearly, she has learned something from her "Gossip Girl" days.

  • Dita Von Teese

    If anyone understands sex appeal, it's Dita Von Teese. This outfit is so alluring, without being too sexy. Her head-to-toe black ensemble shows off her curves (thanks to that belt), while her leather gloves, red lipstick and expertly coiffed hair pull everything together.
