Born a few years ago with (as far as I can tell) Susan Scafidi's fashion law course at Fordham, fashion law is now a "thing." Professor Scafidi now runs a Fashion Law Institute at Fordham,and has a great fashion law blog, Counterfeit Chic. Leonard Budow runs the Fashion Law Blog for Fox Rothschild. Lawyer Charles Colman has a blog called Law of Fashion. And now, the students of the University of Toronto Law School have launched a Fashion Law Society.
As Tim Gunn would say, probably approvingly, "Mak[ing] it work!"
