I'll watch those sometime tomorrow.
I don't think the study of something is the equivalent of knowing and understanding the works of notable people. A good writer doesn't need to major in English or take Lit Crit classes to write well, but they do need to read and familiarize themselves with the work of other authors. It's the human way for creators to build upon the movements of the past and the current, studiously or not.
I presume you didn't study fashion. I didn't either. So hopefully we can get more people who haven't studied fashion to weigh on how to properly learn the subject.
