Who: Anja Rubik.
When: Tuesday, July 5.
Where: The Vogue Paris Foundation gala at the Palais Galliera.
What: A Saint Laurent tux with a tasseled YSL clutch and black pumps.
Why: The competition for best women's tux is a crowded field, but Anja Rubik takes the prize. The cropped, ankle-length pants and oversized tuxedo jacket modernize a classic, elegant look. Shirtless is the way to really do a tux.
