We love Cat Deeley‘s SYTYCD wardrobe as much as dancing on the show and were thrilled when she invited InStyle to take an exclusive peek at her behind the scenes, getting camera-ready. Her two finale looks—a lacy LBD covered in paillettes by Jenny Packham and a voluminous peach tulle dress from J. Mendel—were wildly different, but equally gorgeous. “I want to go from a Dolce & Gabbana, Madonna[-inspired] look to more ‘La Dolce Vita’. Think fountains, think ice cream,” she tells her glam squad as they hover around magazine tears and Web images for inspiration. Watch her get finale-ready above and check out the on-stage outcome after the jump!
