Yasmeen Ghauri catwalking for the Spring-Summer 1992 Gianni Versace Haute Couture collection.THE CATWALK STALK...AND HOW TO DO ITTHE CROSS-STEP: One foot crosses completely over the other.THE PIVOT: When your crossed-over foot hits the runway, twist it toward the inside, giving a swing.THE BOUNCE: Usually on the front end of the pivot, just a bit, nothing too dramatic.THE ARM-SWING: Exudes confidence. At the end of the runway, hands firmly placed just below the hips.THE HIP-SWIVEL: Roll out the hip just a bit at the shift of the weight, then roll back in the other direction, with the inexorable rhythm of a metronome.THE PERFECTLY HELD HEAD: Even with all that action going on below, you could balance a martini glass on Yasmeen's coiffure,and she wouldn't spill a drop.THE GAZE: Straightforward, matter-of-fact, ultra above-it-all.- W magazine.
