Although most of the women flocking to George Tracy these days will tell you in surface conversation that they love his creativity (he specializes in color) and experience (he comes straight from Joseph Michael's in downtown Chicago), the real reason goes deeper than that. It's not the intimate fê te atmosphere of the studio he runs with partner Kim Paul -- not the wine, the music or the guests he invites -- and it's not his ability to size up a person and determine her perfect style. No, the real reason would probably only come out at the end of an evening at George's -- after the candy and the Chardonnay and the hypnotizing head massages -- and even then, it might seem perplexing to some. But not to those who know better. He can keep a secret better than anybody.
