These 19 Sets of Famous Sisters Have 1 Thing in Common: Great Style

Who they are: The definition of fashion royalty, the Courtin-Clarins sisters (from left: Claire, Prisca, Jenna, and Virginie) are the granddaughters of Jacques Courtin-Clarins, who founded the Clarins skin-care company. They also own the Thierry Mugler brand.

Sisters Claire and Virginie have model-like looks, mile-long legs, and eyes you could swim in. Their cousins, twins Prisca and Jenna, are the daughters of the managing director of the company and are equally gorgeous. They can be seen hoofing it from show to show during New York Fashion Week and are collective fans of designers like Proenza Schouler, Alexander Wang, Thakoon, and Rodarte.
