ADDING UP: A fashion label may get the best endorsement when its wares show up on a well-dressed city dweller photographed for fashion industry veteran Scott Schuman's popular blog The Sartorialist. But for those who want more direct brand promotion, Style.com and Men.style.com will begin to sell ads for Thesartorialist.blogspot.com beginning Sept. 1. The partnership is the first time the CondéNet properties have sold ads for a brand outside the company stable. Schuman's blog, where he posts commentary on stylish men and women on the street, attracts more than one million unique visitors a month. He also pens a regular column for GQ and guest-blogs on Men.style.com and Style.com. "The Sartorialist reaches the person who really cares about fashion as a form of self-expression. He chronicles very chic people and his constituency are the people he photographs," said Dee Salomon, senior vice president of CondéNet. The site seeks to attract upscale automotive and consumer electronics as well as fashion brands. Style.com and Men.style.com and The Sartorialist will share advertising revenue generated from the blog. — Stephanie D. Smith
