He was on the faculty of Parsons The New School for Design from 1982 to 2007 and was chair of fashion design at the school from August 2000 to March 2007, after which he joined Liz Claiborne as its chief creative officer. He is well known as on-air mentor to designers on the reality television program Project Runway. Gunn's popularity on Project Runway led to his spin-off show, Bravo's Tim Gunn's Guide to Style, as well as his book A Guide to Quality, Taste and Style.
Tim Gunn appears in in "Escape from Pearl Bailey", after the biology teacher says the student council hired a "pricey Hollywood buffalo groomer" by taking funds from the science budget. Right after the popular girls call Debbie Hyman a fat cow, Gunn reappears to say he has fresh new styles for any bovine.
