DESIGNERS have shrugged off recession gloom with dreams of a more lavish era: Fifties USA.Think glossy leathers buffed to a Cadillac sheen - skirts got the wet-look treatment at Marc Jacobsand Proenza Schouler, while Valentino's lipstick red coat conjured classic car glamour. Prim plaids, from pastel checks to classic tablecloth ginghams, brought a prim and preppy air to Jil Sander and Rochas, while Prada's muscle-car print is the motif to covet. For those who can - a bare midriff will show off those cheerleaders ads. But bare in mind, a mere glimpse is enough. Finally, the only accessory you need to complete your look is a pair of cat's eye sunglasses for a perfect hit of retro Americana.
