In the heart of winter, it's no surprise celebrities are exchanging their brights for sharp black-and-white looks. Diane Kruger
veered slightly at the Chanel
Couture show in Paris wearing a blue school girl number with a charming beret and side-braid. So very Alexa Chung
, no?Jessica Alba
and Kim Kardashian
also joined in the prestigious fashion fun, the first at the Christian Dior
presentation wearing a timeless velvet coat, the latter in a sleek cape, slim trousers, and long leather gloves. Karolina Kurkova
also stuck to this dark monochromatic theme, but in the sexiest way possible. She stepped out in a floor-length slashed gown with a hip-high slit in Switzerland.
Last but not least, Jennifer Lopez
made an unusual choice at the Parker
screening in NYC wearing a little white ruffled dress from Lanvin
's bridal collection. We're still trying to figure out how she makes this sweet look so darn sexy. That's the JLo effect for you! But does she take the cake for best sartorial moment of the week? You be the judge.
