Paris Fashion Week may be winding down, but the front-row fashion shows no signs of slowing. At Louis Vuitton, Sarah Jessica Parker lit up the room in a white lace Louis Vuitton dress and shoes, Fenton bracelets, and Fred Leighton earrings. And over at Valentino, Nicky Hilton paired her sweet but sexy Valentino frock with Christian Louboutin pumps and a ring from Nicholai by Nicky Hilton. Christian Dior's new cover girl, Mila Kunis, opted for the designer du jour, and Jessica Alba perfected her cocktail attire in a one-shoulder, embellished Lanvin mini. See all of these gorgeous looks in today's Fab Flash! On Allison McNamara: Madewell.
