It's her big comeback blockbuster. But for the premiere of Duplicity last night in London, Julia Roberts didn't opt for a show-stopping gown (remember that stunning vintage Valentino Oscar numver?) or an attention-grabbing minidress. Instead, Julia channelled subtle and chic in a Dolce & Gabbana tuxedo... And she's not the only A-lister we've spotted wearing a tux on the red carpet this year. Jennifer Aniston, Amy Adams and Naomi Watts have all chosen to go for androgynous chic in 2009. Hmmm... perhaps they're trying to implicitly demonstrate their earning potential on the big screen? Or maybe it's a credit crunch thing? Who cares. We just love.
