Here, we have a register of historic places. The place gets a plaque on it or sign out front. The owner of the home/building is required to keep it historically accurate if it is not indeed owned by a historical society/town. Because the historical markers are often noted in local travel guides, or in info about the town, people are motivated/required to keep the places up. I will have to pay attention when i next go to a metropolitan area if any relate to fashion. if the town was really known for textiles and garments and it impacted the way of life, I am sure something would get a marker. All in all though, people that we normally think about have passed away in the past 30 years or are still alive, even if they are living in obscurity,so unless they made an impact very young, they are not yet historical enough for a historical marker.
if Coco Chanel once lived somewhere, I am sure there would be a marker eventually, but beyond that, i have no idea. and then something historical had to happen there. (and then how historical it was to a town. if not a lot happened there it would be a big deal, if a lot of stuff maybe not as much.).
