Now I admit, not everyone knows about history very much, or even cares, and that is a subject for other discussions in other places. What I'm about in this post is merely addressing it from the standpoint of the things we wear.
We get so many cues from film, television, and other media sources about what other times looked like, but we tend to forget that the vast majority of them, since they are dramatizations, only present an image of the past that is filtered through a modern sensibility. We don't see the truth of it. In the short term this isn't much of a problem, but in the larger, longer term, it is.
Working where I do, we have a fairly substantial costume supplies area, and lots of fabrics and trims to work with. I routinely get customers into the store who want to create a costume from a particular time. They begin describing what they are after, and I usually realize that where they think what they want is from, is wrong, sometimes by centuries, like the perception that anything before 1600 is "Elizabethan", or that any woman's dress that is long and frilly is "Victorian".
But the most hilarious example of this kind of misunderstanding based on slippery perceptions of time and culture, was one Halloween, many years back. My then partner David, and I had spent a fair amount of time creating a pair of Chinese Mandarin costumes for ourselves. Chinese brocades, the right slippers, and even the correct headgear. Were out and about, having a grand time, when we heard someone exclaim, "Oh look! Rabbis!"
