>> THE MODELIZER — You know Fashion Week season is here when a number of models all change their hair simultaneously: Coco Rocha did an early swap to red a couple of months ago, and Monday night, Vlada Rosylakova took her strawberry blonde redder to a similarly vivid color.  Also parading a new look: Iekeliene Stange, who ditched brown for blonde, and Iris Strubegger, who debuted her cropped cut — supposedly done for a Vogue Paris cover — during the Givenchy couture show late last month.
