Fact: The only thing better than a stylish individual is a pair of stylish siblings. Read on for all the details on our favorite sisters - a combination of in-demand actresses, top trendsetters, and industry insiders – and their sartorially savvy ensembles.

1. The Middletons

Middleton mania reached fever pitch even before Kate married her prince but as the royal wedding celebrations drew to a close –- it became clear that the sisters are serious players in the style stakes. Sharing not just bronzed skin, a taut physique, and brunette tresses, the siblings also love a bargain, often picking up pieces from high street chains like Topshop, Zara and French Connection and preferring to keeps things simple with classic colours and pared-back accessories. With the Duchess showing her allegiance to Alexander McQueen and P-Middy turning up front row at Alice Temperley’s spring runway show, you can expect them to be the subject of continued sartorial fascination.

2. The Olsens

They may be only five feet one apiece, but what the Olsen twins lack in stature, they more than make up for in style. Their stable of brands – The Row, Elizabeth & James, Olsenboye and collaborations with Toms Shoes - have impressed even the most hard-core fashion skeptics and, with their endless layers of Balenciaga, Chanel couture and vintage finds, have practically reinvented grunge-era dressing for a new generation. And now their younger stylish sis Elizabeth is making her mark in Hollywood alongside seasoned actors like Hugh Dancy, and becoming a regular on magazine covers.

3. The Fannings

Whether they’re sitting front row at Rodarte or appearing in Marc Jacobs’ ad campaigns, Elle and Dakota Fanning cementing their status as the new teen idols.

4. The Courtins-Clarins

They arrived to New York last February with suitcases full of Thierry Mugler and Isabel Marant furs, towering YSL pumps, and an endless array of Proenza Schouler PS1 bags. Then they were off to a flurry of fashion shows, and have been perched front row ever since. Virginie and Claire, the statuesque sisters behind the Clarins beauty dynasty, made their official entrée at New York Fashion Week last winter but are now literally everywhere. From Louis Vuitton fetes in Paris to Valentino charity events in Rome, the blond beauties have shown a masterful ability to mix edgy looks with vintage finds to fabulous effect.
