Mary Katrantzou is a designer who takes a lot of risks, and they often pay off. But in the case of this bizarre printed frock-cum-apron worn by January Jones at a screening of “La Revolucion Bleue,” well, the risks certainly didn’t pay off. As Coco Chanel once famously pointed out, before you leave the house, it’s always good to remove at least one accessory. This dress is like 47 accessories too many. Next time, January.
