(click on the images above for price and store information) WHAT: Prada, Louis Vuitton, DKNY, Christian Dior and Salvatore Ferragamo all saw red this fall: red leather at Prada, red wool at DKNY, red baubles & belts at Louis Vuitton, red suiting at Christian Dior and red draping at Salvatore Ferragamo. Call it crimson, ruby, merlot, scarlet or tomato - whatever the shade, make sure it's red hot! WHO: Victoria Beckham was spotted last week at an American Idol audition in a claret red Carmontelle dress from her own eponymous collection while Leighton Meester wore the exact same dress in the exact same shade in July while filming a scene for Gossip Girl. If it's good enough for VB and Queen B, it's good enough for us! BEST BUY: Mad Hatter or not, nothing tops off an outfit like a red hat. That's why we've fallen in love with H&M's red bowler hat (a steal at $17.95). TIP: Siren red lips lite up the Fall 2009 runways (MAC Cosmetics even created a signature red for the fall runways entitled Ruffian Red). For a bold red lip shade under $10 try Maybelline's new Colour Sensational Lipstick in 'Are You Red-Dy.
