Las Vegas might be known for playing up the glitz and glam, but for Sunday night’s Billboard Music Awards, it was all about the little black dress. Whether it was super sexy like Selena Gomez‘s cut-out Dolce & Gabbana gown or futuristic like Fergie‘s strap-heavy Hervé Léger by Max Azria Atelier mini, music’s heaviest hitters went for the classic color. Nicole Kidman added a sweet touch with her long lace dress and side braid, while Beyoncé embodied simple elegance in a Lanvin sheath with over 75 carats of Lorraine Schwartz diamonds! Lady Antebellum’s Hillary Scott skipped the country-favorite gowns for a sleek Mandalay dress with a semi-precious stone neckline. And let’s not forget Kylie Minogue’s heavily embellished Alexander McQueen frock with fringed booties or Britney Spears‘s clean-lined, spaghetti strap Hervé Léger mini. Whew, what a night for the LBD! Take our poll below and tell us who was your favorite!

Has playing dress-up ever looked so fun? In a just-released behind-the-scenes video promoting her new tour, Aphrodite Les Folies, Australian pop star Kylie Minogue tries on a myriad of imaginative stage looks with designers Domenico Dolce and Stefano Gabbana by her side. The Italian fashion house is clothing Minogue for her world tour — the third time they’ve done so — and we love what we see! In the clip above, a glowing Minogue dances in ethereal dresses and over-the-top gowns, flaunts some fun headpieces and stands tall in a few pairs of killer shoes (check out those gold boots), all set to her single “Get Outta My Way.” The tour kicked off in Denmark on Feb. 19, and comes stateside on April 29.

SEE STARS’ WORK STYLE IN ‘LIGHTS! CAMERA! FASHION!’

High notes meet high fashion! Dolce & Gabbana has created the stage wardrobe for Brit pop superstar Kylie Minogue on her “Les Folies Tour,” which kicked off Feb. 19 in Denmark before starting on a world tour. While her last set of tour costumes was designed by Jean Paul Gaultier, this is actually the third time the haute Italian design duo has teamed up with Minogue to create tour costumes; for this show, they used a corset as the base to reinterpret some of their most classic looks for the star. “We’ve revisited iconic Dolce & Gabbana pieces, adapting them to the themes of the tour,” Domenico Dolce and Stefano Gabbana said in a statement. “Working with Kylie has always been very spontaneous and easy. We are given free reign to create because she trusts that we know exactly what she likes. Kylie has always been our piccola principessa!” A sneak peek at one costume (left) appears to be inspired by the title of her last album, Aphrodite. Tell us: Are you excited to see more of the collaboration between Dolce & Gabbana and Kylie Minogue?

We have already seen literal interpretations of menswear for the ladies, but fashion’s boldest trendsetters re-imagined the trend in a variety of ways — all in the last day! The latest iterations of the look range from the risqué to the buttoned-up, but always include stylishly sexy details. Tuesday night, Cate Blanchett opted for a black-and-white look, selecting crisp white trousers and shiny lapels for the IWC “A Night in Portofino” gala in Geneva, Switzerland. In L.A., Camilla Belle was spotted pairing high-waisted tuxedo trousers with a gauzy nude bandeau, revealing her toned abdomen at the premiere of From Prada to Nada. And back across the pond, Kylie Minogue ramped up a classic suit with a sheer blouse, breezy bow and crimped updo. We applaud Hollywood’s affirmation that behind every menswear-inspired look is a strong woman, but want your opinion. Tell us: Are you riding the coattails of the latest menswear trend? Are you ready to add a pantsuit to your going-out wardrobe?–Justine Harman

WEIGH IN ON MORE CELEBRITY STYLES IN: WOULD YOU WEAR THESE TRENDS?

A new trend is in bloom! This season, summer’s pervasive prints have been reincarnated into decadent and glamorous oversized florals. On Monday, Australian pop star Kylie Minogue was spotted out and about in London, sporting a kimono-inspired mohair Dolce & Gabbana black overcoat, dotted with pink and white buds. The style must be contagious because that same night, Kristen Bell stepped out for the U.K. premiere of Burlesque in an equally wild Stella McCartney mini dress, which she tempered with merlot satin pumps. The very next evening, reality starlet Kristin Cavallari turned up at the L.A. premiere of Country Strong rocking a coppery floral bodice gown with newly platinum tresses. And while we love the look on our breezy summer frocks, we’re still on the fence about this blooming winter trend. Tell us: What do you think of oversized florals for winter? – Justine Harman

Kylie Minogue has literally been working some magic as the face of Tous, posing as the the wand-waving, retro pin-up star of the Spanish jewelry brand’s latest campaign, shot by famed fashion photographer Ellen von Unwerth. In this new short video counterpart to the print ads, the Aussie pop star pays homage to ’50s Parisian cabaret, performing magic tricks for an audience dressed in a top-hat, vest, tap pants–and, of course, jewelry from Tous. The singer pulls a rabbit out of a hat and waves her her magic wand to make a handkerchief disappear, before making a shiny pink bauble from Tous’ spring collection appear out of thin air!

Kylie Minogue is working wonders as the new face of Spanish jewelry and accessories label Tous, with sultry magician-themed ads in which the top hat-wearing singer appears to have sawed herself into bits! “We wanted the campaign to be very bold, very fresh and very atmospheric,” Tous co-president Madame Rosa Oriol says of the playful print series, which was shot earlier this month by renowned photographer Ellen Von Unwerth. “To carry off all this radiance and sophistication, we needed the best and for me, that is Kylie Minogue.” In the midst of the February 9 shoot, the 41 year-old Aussie Tweeted, “Hello peeps!! Am in the middle of photo-shoot for the next Tous campaign, photographed by Ellen Von Unwerth. It’s all about…*m*a*g*i*c!! I first worked with Ellen in the mid 90′s….!!! She has great energy and takes gorgeous pics.” We couldn’t agree more. Tell us: What do you think of Kylie’s new Tous ads? – David Caplan

For her first U.S. tour, it looks like international superstar Kylie Minogue will be taking fashion cues from American music’s leading ladies. With couture costumes designed by Jean Paul Gaultier — the same designer responsible for Lady Gaga‘s outrageous VMA looks — Kylie will hit the stage sporting glittering bodysuits and long, sequined trenches identical to these sketches by the designer. And considering the designs’ notable lack of pants and sparkle overload, we can’t help but think Lady Gaga and Beyonce! Tell us: What do you think of Kylie Minogue’s Jean Paul Gaultier tour costumes?

Not to be outdone by Cavalli or Dolce & Gabbana, Jean Paul Gaultier is the latest designer to lend his couture expertise to create custom-made costumes for a singer. The designer has created eight haute couture looks for Kylie Minogue’s “X” world tour that kicked off last night in Paris. Kylie opened the show in a purple chiffon gown from Gaultier’s 2006 collection that was completely couture modified to fit her. Some of her other dazzling outfits include a blue and white “K” logoed cheerleader- and football-inspired outfit complete with padded top, shorts and high heel sneaker shoes. She also showed off a long red satin dress, an equestrian-inspired look that included a black long tailed coat with fringe and over-the-knee leather boots, a sexy Geisha outfit with long Swarowski crystal mesh sleeves, a long turquoise gown with coral heart embroidery, a navy sequin sailor outfit, and finally a crystal embroided corset and black satin pants. With all these amazing costumes, we can’t decide which one is our favorite — maybe the Geisha? Tell us: What costume sounds best to you?

Fresh from a short break, this stylish dance music diva is back on track. Not only has she just finished up a tour and started preparing for the release of her first studio album in four years (the release date is November 26th), but she’s just signed on to represent Tous, a world renowed Spanish jewelry company that specializes in finely crafted ready-to-wear pieces. To show how much she loves the line, she aptly donned their diamond and white gold earrings to the premiere of White Diamond — a documentary about her triumphant return to the stage for her Showgirl Homecoming tour. And while visiting one of their stores, Kylie showed off their 18kt gold Bird ring, $357, and 18kt gold Kaos necklace, $791. Want some Tous jewelry for yourself?

We’re usually big fans of Kylie Minogue’s style, but we aren’t exactly sure her look from yesteday’s Ocean’s 13 premiere in Cannes is museum worthy. While Kylie definitely has the stomach to pull off a sheer midriff panel, the patent-leather belts running up and down make this Dolce & Gabbana frock look a bit dominatrix than fashionista. Throw in the clear platform wedges and we aren’t sure how Kylie can even walk! Tell us: What do you think of Kylie’s premiere outfit? Is it a hit or a miss?
