This week's best-dressed stars[1] stunned in florals. Michelle Obama[2] looked ravishing in a black and red printed Tracy Reese dress[3] , while Alexa Chung[4] proved why she is the queen of style in a peplum dress with interesting details.


But the real star of the show was Sandra Bullock[5] . We're so used to seeing the actress play it safe when it comes to fashion, but this week all of her risks paid off. She made herself the center of attention in a body-conscious neon dress and also wowed in a red gown that did everything to highlight her amazing figure. This leading lady is definitely one to watch out for on future red carpets.


Check out our picks for best-dressed and let us know if you agree!


Sandra Bullock in Alex Perry

Sandy B. has never looked better! Though she is rarely thought of as a fashionista, Bullock turned it on this week in a neon, color-blocked dress. The bright hues look amazing against her summer tan, while her tousled waves keep it casual.


Sandra Bullock in J. Mendel

She's two for two this week! The best part of this ensemble is how the actress accessorized. The rich red dress pairs nicely with her black clutch and black pumps, and though this can be a tricky color combination to pull off, her gown is feminine enough to standup to the dark accessories!


Christie Brinkley

Brinkley is a total babe in this LBD. Though it's so simple, it fits her body like a glove and highlights all her best assets. (We cannot believe this former supermodel is 59!)


Alexa Chung in Kenzo

Nobody does off-duty style quite like Alexa Chung. The model knows how to look effortless in just about anything she wears, and this floral dress is no exception. The cute peplum flatters her figure, while her rosy flats prove that shoes don't need to have a heel to be on trend.


Emily VanCamp

If you're going to go for a solid color dress, something needs to make it extra special. And here, the "Revenge" star did just that. The criss-cross hemline, coupled with the low-cut neckline, adds the perfect amount of visual interest, while her strappy sandals are an unexpected touch.


Lindsay Price

The proportions on this outfit are so right. Price's top may be slightly boxy, but because she is showing a sliver of her tummy, it alludes to her slim figure. Her skirt is also tricky to balance out because of all the volume, but the short hemline ensures that it doesn't add extra bulk.


Olivia Munn in Michael Kors

We love this refreshing dress on Munn! The corset style top draws attention towards her toned arms, while the sweet lace detail on the skirt is the perfect contrast to the sexy bodice.


Ali Larter in Marchesa

Summer is almost over, so now is the time to sneak in a short floral dress. This particular one is great because of the sweetheart neckline, peplum detail and the interesting color palette. Kudos, Larter.


Jamie Chung in Ann Taylor

There is nothing better than a simple outfit that fits seamlessly (especially when it's from Ann Taylor!). Chung's white tank is a great base for her flouncy skirt, and her sleek bun just adds to the polished outfit.


Georgia May Jagger in By Johnny

Mick Jagger's spawn certainly got all the right genes. Not only is the model beautiful, but she is also incredibly stylish. We love the unusual shape of her dress -- it falls just above the ankles and has a little flounce at the bottom. We also adore the color combination (blue and pink are great together), and don't even get us started on those sexy waves.


Michelle Obama in Tracy Reese

The first lady joined her husband for the "Let Freedom Ring" ceremony in a gorgeous floral dress (that reminded us quite a bit of the patterns from the Finnish company Marimekko). FLOTUS looked polished and fashion-forward (we'd expect nothing less) in a dress that showcased those famous guns!

    Outfits like this are why Collins' has become known as a discerning fashionista.

  • Katie Aselton in Zara and Balenciaga

Not to mention her delicate strappy heels and tousled waves complete the look. New York, August 19th Photo Credit: Getty




  • Mayim Bialik in Karen Millen


    Getting dressed as an observant Jew in Hollywood can be tricky -- so many garments are short, tight and revealing. But here, Bialik manages to look stylish and sophisticated. The geometric print on her dress provides some visual interest, while her strappy shoes give her look a little bit of sass. Universal City, August 19th Photo Credit: Getty




  • Christina Hendricks in Badgley Mischka


    There is a reason that LBDs are so popular and Hendricks shows us why. Not only is this dress slimming, but it also showcases the actress' curves in all their glory. We also love the lace cap sleeves which add a vintage touch. Universal City, August 19th Photo Credit: Getty




  • Taryn Manning

    It's nice to see the Vogue EIC out of a skirt suit and donning a bright color. Her modest dress highlights her toned arms, while her statement necklace is the perfect way to draw attention towards her face and that signature bob. New York, August 20th Photo Credit: Getty




  • Erin Heatherton in Toni Maticevski


    The Victoria's Secret model is certainly putting the chic in geek. Though her white lace, high neck dress is beautiful, it's her sexy glasses that steal the show. We love how unexpected they are on the red carpet, especially when paired with a red lip. Sydney, August 21st Photo Credit: Getty




  • Tina Fey in Reed Krakoff


    We've become so used to seeing Tina Fey in weird costumes and casual duds that seeing her in a dress is a little jarring (in the best way). The color blocking on this frock is both flattering and fashion-forward. A+, Fey. New York, August 21st Photo Credit: Getty




  • Olivia Wilde in Osman


    We are "wilde" for this look. The actress' ensemble is uncomplicated: The cut of the dress is simple, the color scheme is monochromatic and her accessories accentuate her look without drawing attention away from it. New York, August 1st Photo Credit: Getty




  • Kate Hudson in Antonio Berardi


    Hudson is on fire lately and this is just the latest in her sartorial successes. Her white dress fits her body like a glove, and the halter neckline draws attention toward her toned arms and glowing complexion. New York, July 31st Photo Credit: Getty




  • Kathy Griffin


    It was a nice surprise seeing Griffin on the best-dressed list this week. We love how she picked this fitted, embellished gown and paired it with minimal accessories. It was a nice departure from her over-the-top ensembles. Santa Monica, August 1st Photo Credit: Getty




  • Vanessa Lachey in Proenza Schouler


    This outfit proves how great a simple black tank and printed skirt can be. The texture of Lachey's skirt adds just the right amount of visual interest, while her metallic strappy shoes add just the right amount of sparkle. West Hollywood, August 1st Photo Credit: Getty




  • Diane Kruger in Mary Katrantzou


    Everything about this look screams perfection.

  • Kerry Washington in Giambattista Valli


    It's no surprise that Vanity Fair's best-dressed star of the year made our list this week. Her mixed patterned dress is a nice change on the red carpet, while her neutral pumps and high bun help keep her frock the focal point. Beverly Hills, August 4th Photo Credit: Getty




  • Naomi Watts in Thakoon


    This is an amazing jumpsuit. It has an ideal cut that's not too loose, but close to the body, while the sheer lace detailing amps up the ensemble. Watts was smart to keep the rest of her look simple with black heels and minimal jewelry. New York, August 5th Photo Credit: Getty




  • Teri Hatcher in Chagoury


    Strapless gowns can be so elegant, especially when they fit properly like Hatcher's. Her metallic dress flatters her hourglass shape, while her matching shoes really ties the ensemble together. Hollywood, August 5th Photo Credit: Getty




  • Priyanka Chopra in Maya Crispen


    Miss World 2000 looked breathtaking in this light pink jumpsuit with metallic gold accessories. Her '20s-inspired hairdo gave a bit of edge to an otherwise feminine look, while her red lipstick married her coiffed locks and dainty ensemble. Hollywood, August 5th Photo Credit: Getty




  • Fan Bingbing in Elie Saab Couture


    The Chinese actress looked stunning in this Elie Saab gown. The delicate embellishments paired perfectly with the dress' light blue and nude color scheme, while the tiering at the bottom added another level of intricacy, rendering the look a design marvel.

  • Lily Collins in Valentino


    Black and white dresses are huge right now, and Collins executed the trend perfectly. She opted for a fitted dress with lace detailing (always a classic) and echoed the neutral color palette in her shoes, tying everything together. New York, August 7th Photo Credit: Getty




  • Kate Hudson in Balmain


    What makes this look so successful is the expert proportions. The chunky embellishments weren't too heavy because of Hudson's exposed skin, and though the hemline was exceedingly short, it was well balanced-out by her conservative top. Hollywood, July 31st Photo Credit: Getty




  • Olga Kurylenko in Lorena Sarbu


    White appears to be the color of the season. The model keeps a rather neutral look interesting by opting for a dress with embellishments and choosing feminine accessories. Los Angeles, July 25th Photo Credit: Getty




  • Kiernan Shipka in RED Valentino


    If only all 13-year-olds were this well-dressed! Shipka is turning heads once again in a cute, textured white dress and a pair of trendy metallic heels. This young teen has a better fashion sense than most adults! Universal City, July 27th Photo Credit: Getty




  • Nina Dobrev in Versus Versace


    "The Vampire Diaries" star has found her color! This orange dress is amazing with her dark features, and we love the combination of gold and orange -- very unexpected. Universal City, July 27th Photo Credit: Getty




  • Quvenzhané Wallis in The Children's Place


    Wallis is making our hearts melt in this adorable and age-appropriate sundress. Not only does this chick have style, but she already has a signature accessory -- a puppy purse! Universal City, July 27th Photo Credit: Getty




  • Jennifer Hawkins in Yeojin Bae


    The Australian beauty queen is drawing attention to all right places. The high slit on her skirt is putting the focus on her toned legs, while her black top grounds the look and adds just the right amount of sophistication. Sydney, July 29th Photo Credit: Getty




  • Sienna Miller in Dolce & Gabbana


    This floral dress is perfect for mid-summer. It's easy and breezy while still being stylish. London, July 29th Photo Credit: Getty




  • Sonam Kapoor in Gucci


    We're not sure where to start with this look, it's so perfect. The plunging, off-the-shoulder neckline creates a nice V-shape which is drawing our eye towards her glitzy necklace, thick brows and expertly coiffed hair, while the teal color is popping against her skin tone. Mumbai, July 20th Photo Credit: Getty




  • Amanda Seyfried in Givenchy


    This is why we love Amanda Seyfried! She manages to pull off fashion-forward looks, while still looking timeless and elegant. The ruffles on this dress are offset by the sleek bodice, and her retro waves and red lipstick make this outfit an instant classic. New York, July 30th Photo Credit: Getty




  • Selita Ebanks


    The model is a total smokeshow in this all-white look. The sheer element and cut-outs on her dress work so nicely because her frock is otherwise demure. We also love her sleek ponytail which is drawing attention towards her gorgeous face. Salzburg, July 30th Photo Credit: Getty




  • Sharon Stone


    This dress is giving us major flashbacks to Stone's performance in the 1992 film "Basic Instinct," and let's just say, the woman is still white hot. New York, July 30th Photo Credit: Getty




  • Miranda Kerr in Wes Gordon


    Head-to-toe orange can be tricky to pull off, so Kerr was smart to mix in a pattern. We also love how her animal print shoes are a subtle attempt at power clashing. Tokyo, July 18th Photo Credit: Getty




  • Kate Moss in Prada


    This is how you dress up a black frock. Although Moss' belted LBD is pretty, it's her neon shoes and animal print clutch that take the look to another level. London, July 18th Photo Credit: Getty




  • Emily Blunt in Wes Gordon


    The "Looper" star moved this ensemble into best-dressed territory with her unexpected footwear. Though many would play it safe and pair this wildly printed sheath dress with nude pumps, Blunt took a risk and added bold red shoes. San Diego, July 20th Photo Credit: Getty




  • Sandra Bullock in Roland Mouret


    We're so used to seeing Sandra Bullock play the funny girl who gets stuck wearing strange get-ups, but here she looks so polished. This red dress looks amazing with her complexion and dark hair color, while the black paneling on the sides is very slimming. San Diego, July 20th Photo Credit: Getty




  • Anna Paquin in David Koma


    Blondes look amazing in black (as proven here). This fit-and-flare dress takes a simple LBD up a notch with its leather trim and shiny embellishments. San Diego, July 20th Photo Credit: Getty




  • Zoe Saldana in Balmain


    We adore this jumpsuit on the "Blood Ties" star. It's dressy enough to wear to an event because of the chain-link straps, ruched bodice and expert tailoring. San Diego, July 20th Photo Credit: Getty




  • Scarlett Johansson in Versace


    'Tis the season to wear neon and floral, and ScarJo does it well. Her busy dress paired perfectly with black pumps and beachy waves -- simple accents that didn't deflect attention from her natural beauty. San Diego, July 20th Photo Credit: Getty




  • Emma Hemming in Roland Mouret


    The British television presenter and former model showed off her trim figure in this skintight turquoise dress. The cap sleeves, slicked back bun and sleek heels scream Hollywood glamour. London, July 22nd Photo Credit: Getty




  • Helen Mirren in Jenny Packham


    All hail, Dame Helen Mirren! The Academy Award winner hit it out of the park in this red Jenny Packham dress. Not only does it fit her body like a glove, but it has the perfect amount of sex appeal. We also love how she paired the bedazzled dress with diamond accessories and nude pumps -- so timeless and elegant. London, July 22nd Photo Credit: Getty




  • Kate Middleton in Jenny Packham


    There is no doubt that this dress will go down in history. The polka dot Jenny Packham dress with cap sleeves, an empire waist and pintucks at the collar was relaxed enough for the new mom, yet sophisticated enough for the prince's grand debut. We're not surprised that Packham's website crashed with people trying to get their hands on this design. London, July 23rd Photo Credit: Getty




  • Naya Rivera in Michael Kors


    We can't stop staring at this outfit. It's flawless. The actress shows off her toned arms in this perfectly-fitted, strapless pink dress. We also love how she threw on a pair of metallic pumps to make the look fashion-forward. Giffoni Valle Piana, July 24th Photo Credit: Getty




  • Nicole Richie in Balmain


    This is a very successful attempt at power clashing. The vertical stripes on Richie's pants elongate her legs, while their neutral color provide a nice contrast to her printed top. Los Angeles, July 10th Photo Credit: Getty




  • Kelly Ripa


    Nude pumps and floral dresses are a great combination. The neutral-colored shoes don't compete with Ripa's printed dress, making this a clean and fresh summer look. New York, July 10th Photo Credit: Getty




  • Emmy Rossum in Carolina Herrera


    The "Beautiful Creatures" star hit a home run with this dress. She balanced out the full printed skirt with a solid fitted bodice, and showcased her long arms with a sleek updo. New York, July 10th Photo Credit: Getty




  • Catherine Zeta-Jones in Maria Lucia Hohan


    Va-va-voom! This is one sexy look. The "Broken City" star highlighted her toned arms and beautiful collarbone in this strapless gown. We also like how the long train on the dress is broken up with lace detailing and a high slit. Los Angeles, July 11th Photo Credit: Getty




  • Miley Cyrus in Marc Jacobs


    Finally, Miley gets it right! Although she's combining a lot of different trends (crop tops, bold stripes and sporty finishes), it works because she has picked a figure-flattering silhouette and a neutral palette. New York, July 15th Photo Credit: Getty




  • Giuliana Rancic


    This ensemble goes to show that a dress can be amazing because of fit. The "E! News" anchor shows off her trim figure in a LBD that hugs her curves in all the right places, while her strappy heels add just the right amount of visual interest. New York, July 15th Photo Credit: Getty




  • Stacy Keibler in Christian Siriano


    A patterned high-waisted skirt is a great way to dress up a plain black T-shirt. George Clooney's ex played up the white in her skirt with a pair of matching pumps and injected a little fun into her ensemble with an animal print belt. New York, July 17th Photo Credit: Getty
