And it's inspiration of plenty of media and fashion designers. I think this example goes against his conclusion.

I am a bit puzzled by these comments. "It is an inspiration for many media," sure, for historical television programs, certainly not for the everyday clothing of our times.

Let's take men's suits. They were made of heavy wool (today heavy wool is demodé, and rightly so because it is very uncomfortable), with three or four buttons (today 3-buttons are rarely seen, and rightly so, except for the 3-roll-2, which is not a "real" 3-button, 4-buttons are nowhere to be seen), the buttons were very high (the Neapolitan suit has high buttons, but much lower than the buttons on the suits of the early 1900s), and the shirts had high paper collars, which are nowhere to be seen. And the hats?

There is nothing current that recalls the clothing of those times.

The clothing in "Peaky Blinders," which is a decade older, is something like a fedora nowadays, please.

Men have a very limited wardrobe range, and most of them does not care about it. You have to look a the woman clothes.
