Since her breakout roll as a 20-year-old in the dreamy candy-colored film "The Umbrellas of Cherbourg" in 1964, and now more than 100 films later, French actress Catherine Deneuve has been burned into the minds of many generations around the world as the ultimate style icon.

For over four decades, the Oscar-nominated actress balanced her blond bombshell good looks with a fashion sense dominated by smart coats, cable-knit sweaters and secretary blouses, that is completely her own.

While she told StyleList in a recent interview that she doesn't "dress for style," but rather "to be dressed," we think that might be precisely the reason this onetime face of Chanel No. 5 and muse to Yves Saint Laurent always looks so effortlessly chic.

In celebration of her new flick, "Potiche," a comedy set in 1977 Paris (read more about it, plus our interview with Deneuve, here), we're taking a look back at her best sartorial hits (and rare misses) over the years.

Meanwhile, to study the wardrobe of another French fashion icon, peep the "Style Evolution" of first lady Carla Bruni-Sarkozy.
