@bloop @ThrowawayAI Not trying to dox myself but there's clothes makers now who are doing new things, giving old styles new folds and stitchings/materials to give way more mobility in the shoulders. In theory a person could make a fighting suit, a suit someone could do gymnastics in with no problem like binding up, it's just that there's not a big market for it so it's only custom jobs or niche makers here and there.
A suit is social armor, a way of covering status and presumed success to give the wearer more authority and respect without necessarily having to prove themselves.
Like it or not clothing is as much for social purposes as practical.
