Pretty much what title says. It seems as though with the passage of time, clothing became less and less complex (smaller, bent collars, small lapels).
Is there documentation on why these changes occurred and how they evolved into the modern style of suit?
Beau Brunel Brummel, a British aristocrat, is more or less the father of the nineteenth century male fashion. He was the one to push for more sobriety and simpler shapes, in opposition to the eighteenth century male "habit" inspired by French fashion.
Basically the real change in male fashion was to go from French inspired clothes to British inspired clothes.
That would be great. I'm trying to learn a little French, but I'm fluent in Spanish so there are a lot of similarities!
I'll keep looking into him, as well. Thank you!
