Oh. My. God. Why are French people so cool? Is it just us? No it couldn't be. It's just Carla Bruni-Sarkozy, the First Lady of France, doing her thing at an AIDS event in this incredible strapless, cobalt blue gown.

What else would a cool, chic Parisian woman wear but an equally cool, chic Parisian designer? This blue dream of a dress is, of course, by none other than the French fashion house Yves Saint Laurent. The world's first ladies are now becoming a fashion force to be reckoned with. Oui! Oui! Oui! We love it!
