A charming Isla Fisher stars in a knockabout farce opposite Hugh Dancy. "Confessions of a Shopaholic" is a cleverly constructed catwalk of a romantic comedy that's a lot like that perfect outfit -- the swirl of a skirt from Miu Miu, the Marc Jacobs jacket, the Louboutin slingbacks and the $3,000 Gucci bag, or in my case, the Gap jeans, Free People T-shirt and Uggs.
