Yves Saint Laurent Beauté's creative director of makeup, Lloyd Simmonds, captures the spirit of the Parisian brand with this Fall/Winter collection that's the ultimate in bad girl chic. With kajal-smudged eyes, matte black nails and a dose of atttitude, think of her as the world's prettiest punk.

Kajal Eyes

The star product is the Couture Kajal, a three-in-one kohl pencil, liner and eyeshadow that the brand has produced in four shades. Simmonds says that "it glides on easily on the eyes, and gives a sexy, smudgy effect that looks great on every woman." He recommends using the Couture Kajal as a base for any subsequent eye makeup instead of primer, as it adds depth and staying power to a smoky eye.

But in the name of French elegance, one should always tone down the rest of your makeup when wearing such strong eyes. Think of it as the facepaint equivalent to Coco Chanel's sartorial advice on always taking one accessory off before heading out. Says Simmonds, "Go for a bold look for the eyes, but play down the finish of your skin, keeping your complexion minimal and going light with your foundation and contouring."

For that, turn to products like the Poudre Compacte Radiance Perfectrice Universelle. It's so finely-milled that it adds no additional weight or texture to the skin while cutting out any shine. And if you're all thumbs when it comes to nail art, try the brand's nail stickers. Simply peel them off, stick them on and trim them to size. After all, no rock chick worth her salt spends too much effort on looking good.
