As a big fan of Bravo's Project Runway, of course, I'm a big fan of Tim Gunn, the voice of reason ("Carry on") in what can sometimes be a crazy, overly dramatic reality TV show about fashion designers.

He says it like it is, and while his taste is impeccable, he doesn't come off to me as pretentious. In fact, according to a recent interview with New York Magazine, Mr. Gunn even gives the thumbs up to costume jewelry such as cubic zirconia: "I hate to say this because I'm so respectful of brands, but why spend $2,000 on the Chanel bag? I don't believe in jewelry for men, but women's jewelry-what's wrong with cubic zirconia? I say, if it looks good and it works, do it. "
