I can't remember?, but my love for specific designers started at my late teens. Before I got into fashion, I was really into drawing, music and movies. My love for punk music made me discover Vivienne Westwood... my favorite Japanese illustrators and musicians liked Comme des Garçons, so I discovered Rei Kawakubo...
I'm still not familiar with a lot of the bigger brand names. I haven't read any of Coco Chanel's biographies, because her work has never really 'touched' me. I started buying loads of fashion designers' biographies thanks to this bookstore in the Old Port of Montreal (carrying the Assouline books) when starting college... so I guess my passion started when I was 17.
