Having managed the technology solution for jeans fit clinics at Gap, I know firsthand the importance of fit to an apparel consumer. An emerging niche of online companies aim to help consumers find perfect fitting apparel. One company, venture-backed Zafu.com, has analyzed the fit of hundreds of jeans from diverse brands on thousands of women, and when a consumer plugs in her particular measurements, and style and size preferences, the site predicts, with an alleged 94% accuracy, a perfect fit. The site links to third-party sites that carry the jeans.
