Of course Kirstie could be referring to her shoe size..... I shop at Barney's and Saks on occasion, but mainly at Macy's and Nordstroms. While I'm not tiny by any stretch, at Macy's and Nordies I'm an easy 8. At Barney's, Saks, and Nieman's I'm a 10 or 12 with no problem, with the exception of my pride. Upscale stores tend to have runway designers and runway sizes. My experience has always shown the sizes run much smaller at high end department stores. Maybe Xanadu makes Kirstie's clothes!
