Wilde, Watts, Diaz and Froggatt

This could be the red carpet look of the year. Olivia Wilde’s ALC jumpsuit has a seriously plunging neckline, yet the demure actress still manages to look sophisticated with pared back make up and simple blue velvet Gio Dev pumps.

Naomi Watts chose a Calvin Klein nude dress from the Spring 2013 collection for the special screening of ‘The Impossible’ at the Museum of Art and Design in New York City. Love the dress — but it’s a shame it didn’t fit her tiny frame.

Cameron Diaz was casual chic perfection at the after-party for Tarantino’s Django Unchained in New York. Dressed in ALC black slacks, a sheer white top, and a collarless Helmut Lang blazer, she looked slick and sophisticated.

Could this really be Downton Abbey’s Anna Bates? Joanne Froggatt shows her stylish side at the Hollywood Reporter’s screening of the hit TV show in California in eye-popping turquoise, complete with blonde tresses and sun-kissed skin.
