Nobody does sexy suiting like Scarlett Johansson [1] (in fact, nobody does sexy, period, like the smoldering star). She proved that point again by turning up tonight at the César Awards in a sleek black Dior ensemble. She wasn't the only one giving us a lot to look at.

A serious occasion calls for a serious style moment. And nobody gets down to business better than Joshua Jackson [2] and Diane Kruger [3], who dressed for the mood when meeting with the Dalai Lama. They were joined by Camilla Belle, Nikki Reed [4], and Lupita Nyong'o, who's been having a very busy style week.

A day earlier, two dresses proved better than one, when our favorite new style crushes united for the LA Non-Stop premiere. Lupita and Michelle Dockery reminded us why we're so enamored by them, with playful red carpet dresses and attitudes to match! On the other side of the globe, it may technically be the year of the horse, but that doesn't mean we need to cast aside our favorite serpentine accessories. That's especially the case given Bulgari's standout jewels, as demonstrated by Naomi Watts [5] at the label's Milan, Italy, presentation. The actress positively glowed in a dangerously coiled diamond design that she accessorized with the label's snake-head clutch.

Statement jewels found a home on other weekend red carpets, too, when Amy Adams [6] and Kiernan Shipka stunned at the Costume Designers Guild Awards, and Lupita joined Kerry Washington [7] for the NAACP Image Awards. See all the stellar looks here!
