what you posted above was not "pre-Victorian," it was more like "renaissance"
Well, that's a late 18th century coat, which would make it pre-Victorian indeed (perhaps pre-Napoleonic would be more accurate).
Here's an example of the more non-westernized forms of Chinese men's fashion.
I have a couple of oriental-style outfits like this, but I can't wear it to a corporate luncheon that I'm going to tomorrow because all the other guys will be wearing boring, bland suits.
This also reminds me: the male multimillionaire celebrities of today are much wealthier than the nobles of past ages. They have easy access to all the richest fabrics and talented designers in the world. And yet, when they show up to events like the Academy Awards, they all wear the exact same penguin-style tuxedo, even the fashion designers themselves. I just don't get it.
