I’m OK with the suit going but damn, without those there’s not much left for guys to wear that’s not athletic wear of some kind or another (and hell, sport coats kinda are anyway)
Sport coats are athletic wear? To me, a sport coat is the same thing as a suit jacket, with the only difference being that a sport coat isn't the same color as your pants. It will literally become a suit jacket if you put on matching pants.
For example, a sport coat, very much unlike athletic wear, will prevent you from raising your arms too high with its big squared shoulders.
Then our most popular outerwear shirt, the T-shirt, used to be underwear with a strong military association, and came into common use the same way much of the rest of our modern fashion did: youth culture, which AFAIK is also how we got the blazer (dad's orphaned suit jackets) and two-button and especially two-roll-three suit jacket styles (kids wearing hand-me-down 3 and 4 button suits and orphaned jackets "casually" with fewer buttons done up).
Yes, but also the collar is buttoned down because those shirts don't have bones and are not starched.
I'd even settle for denim if we must play at working on cars for women to accept it as fashionable. Maybe then I can finally have my cargo pockets back!
