In our latest Model Diary, Polish stunner Kasia Struss takes us behind the scenes at some of the most hotly anticipated shows of Fashion Week. In one packed day, she prepares to trot down the catwalks of Carolina Herrera, Donna Karan, and Marc Jacobs. Along the way, she shows off the natural makeup at Y-3 and silver-streaked hair at Herrera — as well as a brief but glorious close-up shot of the twisted garb at Rodarte. A Carolina Herrera show, she's told by a sage photographer, is "better than Led Zeppelin." See the pre-show preening in the video.
