Salma Hayek Pinault and Penelope Cruz
You may not know this, but Salma's husband literally runs the fashion industry. He's the CEO of Kering, the company that owns basically every brand you can think of (ever heard of Gucci, Saint Laurent, or Alexander McQueen?). Salma Hayek and Penelope Cruz have been friends for years and the two could not be more of a stylish pair. It probably helps that they can get their hands on whatever designer clothes they want.
