Karen Walker has taken over our Fash Cab, and we simply couldn't be happier. The New Zealand designer didn't hesitate to buddy up with us and spill on her newest ventures (Karen Walker home decor!), some intense pre-NYFW cleansing rituals, and breeze through our Lightening Round without even as much as a hesitation. Overall, our new Fash-Cab friend is a breath of fresh air who charms us on and off the runway. Just don't challenge Karen to a Scrabble match. She'll take you down.
