While it sold out within hours in London, American women coveting the blue Issa dress Kate Middleton wore to announce her engagement are in luck: Starting immediately, reservations can be placed on the $535 long-sleeved silk-jersey dress on net-a-porter.com, with orders expected to be shipped in January. For those of you lucky enough to be in London, you can pop into Harvey Nichols, Matches or Fenwick on Bond Street (where it’s believed the princess-to-be picked up hers), but expect to be put on the wait list as this dress has gained superstar status, with high street copies selling out everywhere since that historic Nov. 16 announcement. And while that particular dress has caused a global sensation, designer Daniella Helayel refuses to comment on whether it’s hers or Kate’s favorite. “I don’t have a favorite,” Helayel tells PEOPLE exclusively from her Chelsea studio, where the phone has been ringing off the hook since that appearance. “I always admire the styles and colors Kate chooses to wear. She has great taste.” –Suzanne Zuckerman; reporting by Monique Jessen

When budding singer/actress Willow Smith isn’t busy whipping her hair, the fearless fashionista loves to flaunt her edgy personal style. Recently, we spotted her in a super-trendy outfit, including red hot boots and a military-inspired blazer. Check out the details in our Moms & Babies section.

There are a few luxe items in which every fashionable woman should invest: a great handbag, an elegant timepiece and a timeless Burberry trench coat. Perfect for inclement weather and sunny days alike, a well-made trench can mask imperfections, create a perfect hourglass shape and pull together even the mishmashiest of outfits. The only gripe we actually have with the classic coat is its ubiquity. That’s why when we spotted style icon Emma Watson arriving at New York’s JFK International in a khaki topper with buttery leather sleeves, we were determined to learn more. As it turns out, Burberry Creative Director Christopher Bailey designed the one-of-a-kind jacket specifically for Emma. The gracious star (and face of Burberry) appreciatively Tweeted, “Wearing my favourite trench that Christopher Bailey @Burberry designed for me. Love it!” So while for now we will have to make do with salivating over Emma’s masterpiece, come next spring, e-shoppers will be able to customize their very own. And though details are still hush hush, we have been informed that the ‘Burberry Bespoke’ service will be a fully integrated, innovative digital platform that enables the personalization of the iconic Burberry trench coat. All we know is, the queue starts here! – Justine Harman

Taylor Swift seems to have found her sartorial partner-in-crime in designer Tracy Reese, sporting three different looks from the feminine line—all in one week! First, while appearing on Live! with Regis & Kelly on Oct. 27, the flaxen blonde donned a nougat lace confection ($288) with a black waist tie, before changing into a red polka dot cap-sleeved prairie dress for a private concert at JetBlue’s Live from T5 in New York.

And if you’re loving Taylor’s sweet-yet-chic look, we’ve tracked down where to score her dresses!

Last night’s episode of Gossip Girl might have been all about Serena van der Woodsen’s (played by Blake Lively) affair gone wrong, but we couldn’t take our eyes off of Blair Waldorf’s (played by Leighton Meester) sophisticated winter white look. While playing the supportive girlfriend to Chuck Bass (played by Ed Westwick), Blair accompanied him around the city looking the picture of Upper East City chic wearing an ivory Escada coat over a houndstooth Alexander McQueen blouse, Lanvin cap toe pumps and toting her coveted Valentino bag. We love Blair’s look, but unfortunately, we don’t have her budget! So forget the labels, we found Blair’s head-to-toe look with nothing over $100! Shop Blair’s style from last night here.

To ward off chilly London temps, Kate Hudson, who is in the U.K. to promote her new movie Nine, came prepared with an arsenal of chic, highly covetable outerwear. First, Kate turned up in a sleek black cashmere Jasmine Di Milo number for a shopping trip, only to amp things up for evening in a studded Temperley London jacket worn over an ornate (and color coordinated) black and gold Topshop party dress. Keeping up her cozy-but-glamorous vibe, Kate stepped out the following day for a radio interview in a girly, ruffle hemmed wrap coat, again by Jasmine Di Milo, on top of a pink leopard print shift by Simone. We love all her looks, but can’t exactly afford the same big ticket items as Kate…so we tracked down similar items for far less. Click here to shop for coats like Kate’s.

Now that Serena van der Woodsen (played by Blake Lively) is free from the restraints of her high school uniform, her daytime look for dabbling in the world of politics consists of sharply tailored, big-name designer items paired with more affordable pieces. To celebrate Thanksgiving with family and friends, Serena opted for a sexier, high-fashion vibe. For a dinner filled with more drama than turkey, Serena chose a plunging, curve-hugging Stella McCartney jumpsuit complete with a lace front panel. While we wouldn’t suggest wearing this to a holiday dinner with your parents present, Serena’s fearless jumpsuit is perfect for a night out! Shop Serena’s Thanksgiving look for less here!

If Vanessa Abrams thought college would free her of Blair Waldorf’s wrath, she was dead wrong. While trying to sabotage each other’s chances of giving the NYU freshman toast, Gossip Girl‘s rival starlets, played by Jessica Szohr and Leighton Meester, might have lost their cool, but at least they kept their style. Blair dreamed of her defeat while wearing a jeweled Reem Acra plum gown. Vanessa, on the other hand, came close to her first victory over her arch enemy while sticking to her signature boho chic in a tribal-print Nanette Lepore top, American Apparel liquid leggings and Dolce Vita booties. And even though both stylish freshman were beat out by a Herve Leger-clad Olivia Burke, played by Hilary Duff, we still loved their competing looks so much that we had to find them for you.

Dan Humphrey, played by Penn Badgley, isn’t the only thing Gossip Girl‘s two most famous blondes have in common. Serena van der Woodsen, played by Blake Lively, and new girl Olivia Burke, played by Hilary Duff, ditch their glam lives for quiet time out of the spotlight. But the designer labels stay with them. Olivia sported a purple Intermix ruffled dress and Christian Louboutin sling backs. Serena, on the other hand, put a conservative spin on her luxe labels by pairing a curve-hugging Herve Leger bandage skirt and sparkling Valentino purse with a Topshop boyfriend blazer to interview with Tory Burch.

Gossip Girl‘s resident fashionistas might not have seen eye-to-eye about boys on last night’s episode (ahem, Carter Baizen), but Leighton Meester‘s Blair Waldorf and Blake Lively‘s Serena van der Woodsen did manage to agree on one thing — color! Leaving Vanessa Abrams’s boho fashion influences in the dust, Blair headed back uptown, happily slipping right back into her signature, sophisticated style with a canary yellow Diane von Furstenberg wrap top and a black-and-white Vince skirt. Even Serena got into the bright mood, mixing sapphire Zara sandals and a turquoise Treesje clutch with a navy Matthew Williamson dress. We love the way Blair and Serena incorporated bursts of color into their ensembles so much that we tracked down their looks for you. Click here to shop their style for less!

New season, new school, new look for Gossip Girl‘s Queen Bee Blair Waldorf, as played by Leighton Meester brought her Upper East Side style down to NYU, but her Victoria Beckham peplum dress and matching headband didn’t play quite as well below 14th Street. Now, for Waldorf’s arch-enemy Vanessa Abrams, played by Jessica Szohr, the transition from Brookyn to campus was a little bit easier with her signature funky style, like last night’s Joie denim cargo shorts and a floral DVF print tank. No wonder Blair took a cue from her new floormate and switched into a pair of brass-button Milly sailor shorts and abstract striped DVF top! We tracked down their chic outfits for a whole lot less — not all co-eds have that kind of budget!

The Oscar winner has worn everything from Oscar de la Renta to Donna Karan, but for the cover of her new album, which hits stores in September, Jennifer Hudson proves that she’s no fashion snob, opting for a simple $36 glitter-striped American Apparel dress. Bargain hunting’s nothing new to the “Spotlight” singer, who readily admits to an obsession with affordable British chain Topshop. But while the cotton dress may have been a bargain, when it came to accessorizing the look she went decidedly high-end, glamming it up with a $475 LAI Vamp belt. We think Jennifer’s cover frock is even more flattering than some of her designer dresses (Oscars anyone?). And what we love most is that it’s a look we can get too! Click here to buy J. Hud’s dress at American Apparel. Interested in more affordable star fashion? Check out other star styles under $100 here including looks from Jennifer Lopez, Eva Longoria, Carrie Underwood and more.

Madonna‘s bold new make up look for her latest number one album, Hard Candy, is already instantly recognizable. So we spoke to Gina Brooke, artistic director of Shu Uemura, who created the look to get the exact step-by-step she used for the superstar’s album cover style.

Even skin tone with Face Architect Smoothing Liquid Foundation, $42. Next, make the eyes the focus. Apply Pressed Eye Shadow in M Beige 800, $20, above the eyelids using a Kolinsky Brush 11, $135.

Curl lashes with an Eyelash Curler, $19, before applying Basic Black Mascara, $28, beginning at the base and rolling the brush through the tips of lashes. Apply Soft Cross Lashes, $20, to draw attention and enhance the shape of the eye. Finish with subtle lips by applying Rouge Unlimited Crystal Shine in PK 301S layered with Gloss Unlimited in BG 930N for a chart-topping look.

The Gossip Girl‘s mixable separates aren’t just cute, they’re the perfect transition into spring.
