Costi, please.
A long time ago, in the early 1900s, some person who thought that he dressed in 'classic style' from the 1850s also likely thought that the young men of the new century were wearing...
rags. How dare they! Those ignorant fashion victims!
So TF is very expensive stuff. Big deal, so are most of the garments seen here. I have seen TF garments in person, and it is extremely well made RTW. It has a very precise aesthetic, designed to appeal to a very narrow spectrum of men. So it is not for you, but hey - it was never targeted at men like yourself in the first place. And believe it or not, the people who buy TF (or any similar product) are not going to want to dress like you, even if they had the choice, even if they were so 'informed' as to the historical appropriateness or the technical reasons.
There is enough space in the world for all of us - those who prefer the latest fashions, those who dress in a manner they consider classic style. Those who prefer lighter cloths, and those who prefer heavier cloths. Yes, fashion does have its excesses, but if the barriers, the boundaries are not pushed by designers like TF and Lagerfeld, then little things here and there are never invented/designed, and never become incorporated into what we consider 'eternal style'.
After all, once upon a time, were things which we take for granted today (such as cuff buttons) not considered rather...
outre?
Clothes are after all a reflection of our personality, and how boring would it be if we were all... alike, forever unchanging?
