The Kardashian sisters hit the Beach Bunny Swimwear 2011 Collection debut at Mercedes Benz Miami Fashion Week – Swim, last Friday. Not only did the girls watch the models parading down the runway, they sported OPI nail polish just like the catwalkers. Khloé, an avid OPI wearer, wore Bubble Bath, a soft milky pink. Kourtney choose Over the Taupe (left), a gorgeous mushroom-y shade—and the very same hue worn by all 14 models in the show.
