Former Gossip Girl star Blake Lively, who was the face of Dior and just happens to have a Christian Louboutin heel named after her, mixes Manhattan glamour with LA laidback-girl chic to stunning effect. Cara Delevingne made an appearance on nearly every single catwalk at Fashion Week last season, but it's her grungy, off-duty model look and rock chick red carpet appearances that get people talking. She was also named most searched-for term by Google in 2013. The former face of Gucci, Charlotte Casiraghi's reputation as a fashionista royal extends well beyond Monaco. The new mum regularly tops best-dressed lists with her elegant yet effortless ensembles. It's no surprise that David Beckham picked up the Most Stylish Man at the GQ Men of the Year Awards earlier this year — never short of impeccably dressed, David has also fronted campaigns for Belstaff and has his own bodywear collection with H&M. Since joining the X Factor judging panel, Gary Barlow has seriously stepped his style up. Week after week, the musician has impressed with his well-tailored suits and immaculate accessories. Harry Styles recently fought off tough competition from David Beckham, Alexa Chung, Kate Moss and his former flame Cara Delevingne to be named Best Style at the British Fashion Awards for his grungy, laidback cool vibe. The face of Dior, Vogue's September Issue covergirl and constant best-dressed list topper, Jennifer Lawrence is officially fashion's darling. The Hunger Games actress is often praised for her simple yet elegant style that makes her a red carpet favourite. Never afraid to experiment with androgynous pieces, Jessica Alba is one of Hollywood's fashion finest. She also has a thing for bags. "I can’t even talk about how many I own," she said recently. "It’s a problem. My husband talks to me about it. 'Is it really necessary to have another bag?'" Kate Middleton rarely puts a fashion foot wrong and is highly praised for recycling expensive designer items — like this black lace Temperley dress — in her wardrobe. She also likes to mix highstreet pieces with designer items, recently sporting a bespoke cream Roland Mouret gown with a £19.99 Zara necklace. Since giving birth to her baby daughter North West back in June, Kim Kardashian has wowed in a series of fashion-forward outfits that show off her enviable curves. Crop tops and skintight skirts have played a big part in her post-pregnancy wardrobe, as have oversized coats and white dresses. Widely considered the most stylish Kardashian sister, Kourtney often steps out in head-turning fashion-forward outfits from the world's most high-profile designers. She recently stepped out with her daughter Penelope in matching leather jackets. Neutral colours, draped styles and barely-there sandals, former Made In Chelsea star does glossy SW3 style to perfection. She wore a vintage lace Alice Temperley gown to marry her rapper love Professor Green back in September. Fashion designer Nicole Richie has both funky boho chic and on-trend elegance down to a tee. She also appeared as a judge on NBS's Fashion Star for two seasons. The ultimate trendsetters, Mary-Kate and Ashley Olsen may be the most stylish twins to ever grace the planet. The pair, who own fashion lines The Row and Elizabeth & James, are widely praised for their effortless style that consists of oversized sunglasses, boots, loose sweaters, and flowing skirts. Former OC star Rachel Bilson is an expert at effortlessly layering edgy and ladylike pieces with ultra-fashionable results. Speaking about style, she once said, "It's hard for me to wear high-waisted shorts or jeans because I'm short. I love a nude shoe with a skirt or dress, because it elongates your legs. Anything that makes me look taller." Sienna Miller has been on the style radar for a long time. She shot to fashion fame for her boho chic — she pioneered the gypsy skirt and gold disc belt ensemble — but has more recently been rocking a grown-up elegance. There's no such thing as off-duty for fashion designer Victoria Beckham, who never looks anything short of immaculate, often in her own designs. The star favours black, tailored pieces and skyhigh heels.
