Think you have to be a special kind of person to think the suits from a few years ago “look stupid” now. But I guess that’s also the kind of person buying the £500 tshirts linked in the article.
Cuts have changed a lot in the last 5 years due to a generational shift. Millennials are now coming into their prime as producers. The 2010s saw increasingly slim tailored cuts. The 2020s are all about drape and how you can construct a shape, not reveal it.
There is always going to be a generic cut of suite that changes slower for the person who wears suites a few times a year. But for more fashion oriented cuts, there has been a change for someone that wears them everyday.
I think you confused my statement of caring what other people think about my suit, to wearing a suit. I wear suits. I just don't care what the fashion around them is.
