Her costumes in Confessions of a Shopaholic may be a bit on the Carrie-Bradshaw-at-a-jumble-sale side, but Isla Fisher got it very, very right at the premiere of the film. Dressed in an iridescent green strapless dress by Matthew Williamson with matching slingbacks, she looked every inch the Hollywood star, finishing the look with poker-straight locks and bling earrings. Isla's fast becoming one of our red carpet faves. She may not be uber-adventurous, but she always looks beautiful.
