I know very little about fashion. As an academic, I rarely have to wear a suit and tie (although I usually try to dress reasonably — no T-shirt or jeans — because I’ve found my students take me more seriously if I dress the part). But I do know one thing about high fashion. If this ever really does become a trend, our civilization is doomed. Forget global warming or antibiotic-resistant bacteria or SARS. We’ll just close up shop and go extinct.
