This week's best-dressed list was filled with stars who took fashion risks that paid off. Gabrielle Union dared to show a little skin (okay, a lot of skin), but managed to make it work by wearing a sophisticated silhouette, while Diane Kruger went for a big ball gown that achieved the perfect balance.
Though there were many looks from this past week that were frame-worthy, our personal favorite has to be Coco Rocha's ensemble. The model looked drop dead gorgeous in a navy gown, proving that sometimes the fashion stars do align.
Check out our picks for best-dressed and let us what you think.
Gabrielle Union in Pierre Balmain
Va-va-voom! Union has shown the perfect amount of skin in this look. The low neckline and high slit aren't too much because of the dress' long and loose nature. We're also obsessed with her strappy shoes which are elongating her legs.
Coco Rocha in Greta Constantine
Everything about this look is perfection -- the body-skimming fit, the interesting architectural cut-outs, the rich navy color, the bold orange lipstick -- it all just came together.
Hailee Steinfeld in Prabal Gurung
The fashion risk-taker stepped out in a dress from Prabal Gurung's Spring 2014 collection, and she really let the gorgeous frock shine. Steinfeld was smart to keep her makeup and accessories simple, drawing focus to the interesting detail work in the gown.
The print on Ackerman's white skirt is what makes this ensemble. Though she went simple on top, sporting a black tank, minimal makeup and low-key jewelry, her patterned skirt is what made this outfit one to remember.
Diana Kruger in Prabal Gurung
Now this is a gown. The color-blocking on the dress is very figure-flattering, while the voluminous bottom is perfectly balanced out by the tight bodice.
Michelle Dockery in Erdem
It's nice to see this "Downton Abbey" star looking so sweet. We love the short floral dress and bright yellow pumps -- afterall, it's not that cold out yet.
Emma Roberts in Stella McCartney
If this dress were black, it would have been boring, but this vibrant orange color is what makes this simple gown a knockout. So many stars stick to neutrals on the red carpet, but a bright, bold hue can easily take a dress from ordinary to extraordinary.
Stacy Keibler in Pamella Roland
This look is incredibly sleek and sexy -- from Keibler's slicked-back hair and burgundy lipstick to her tight-fitting dress with leather accents.
We always forget that this "Mad Men" star is only 13 years old, as she has impeccable taste. Navy and black is one of our favorite color combinations (it's so sophisticated), and we love how she's chosen a classic shift shape with batwing sleeves, very unexpected.
Miranda Kerr in J. Mendel
Kerr can do no wrong. The model combined a few different trends (sheer, cut-outs and a midi length skirt) to create an outfit that was fashion-forward and flattering.

More celebs who made the best-dressed list:
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.
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.
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.
Sometimes all you need is an LBD and red lipstick. Dockery's look is incredibly sexy and subtle, we just can't get enough.
Olivia Wilde in Cushnie et Ochs
Though we admit that Wilde's dress looks a little summery, she wore it in LA, which is undoubtably warmer than the East Coast right now. The delicate floral print is so pretty, especially when paired with the actress' tousled locks and minimal makeup.
Kate Bosworth in Christopher Kane
Without the embellishments, Bosworth's dress isn't anything special. But the added detail around her neck pulls the focus towards her face, while the detailing at her waist helps to define her shape so she doesn't get lost in all the loose material.
Diane Kruger in Chanel
We can't say we're surprised that Kruger managed to find herself the perfect strapless gown. Though the dress has a lot of colorful accents, it's short hemline and simple silhouette keep it from being over the top.
This dress is perfect for the actress. The voluminous bottom is balanced out nicely by the fitted bodice, while the subtle rhinestones help to keep the gown interesting.
Ashley Madekwe in Theory
There is something so effortless about this look -- it's as if she just threw it on, without giving it much thought, and voila! But her red strappy shoes, which add a nice pop of color, let us know that this lady is a discerning fashionista.
Sandra Bullock in Dsquared²
Bullock is looking better and better with every red carpet appearance. We love this lingerie-inspired LBD. Not only does it fit her body like a glove, but it's also a subtle take on the underwear as outerwear trend.
Well, that's one heck of a cut-out. Though the Victoria's Secret model is baring a lot of skin, the long hemline and flowy skirt compensate for the sexy top.
Demi Moore in Salvatore Ferragamo
Moore's style is only getting better as she gets older. This rich, navy halter dress is fun, yet still age-appropriate.
There are so many things that are perfect about this look: The black and white color blocking is extremely flattering, the light draping accentuates her small waist, while the keyhole detail at the top breaks up all the material.
All that glitters really is gold, or at least, this dress. The embellishments, halter neckline and neutral color are the trifecta of chic.
Kate Beckinsale in Donna Karan
There are few ways you can go wrong in a plunging red wrap dress, but the vibrant color and lines on this gown make Beckinsale stand out for all the right reasons.
Reese Witherspoon in Calvin Klein
We adore the simplicity of this look. The bold dress with the thin white line is not only captivating, but draws our attention to the actress' beautiful updo.
Taylor Schilling in Zuhair Murad
The proof is in the pudding -- Taylor Schilling is not only a talented actress, but she also has killer style. Even though it's way past Labor Day, the star's white dress works because of the black accents and long sleeves.
Viola Davis in Escada
The fit of this dress is perfection. It hugs the Academy Award-nominated star in all the right places, and the V-neck complements her physique. Davis has also mastered the art of picking the right hue for her skin tone.
Miley Cyrus in Marc Jacobs
We were starting to forget what Miley looked like with clothes on. This dress is so sexy without showing too much skin -- she's on the right path.
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.
