With today's fast fashion churning out clothes with shorter and shorter lifespans combined with our cultural love of replacement over repair, we basically already do.
I always find it amazing that people actually give a fuck about fashion and don't just wear what they like. I don't get it, fashion is supposed to be a statement about yourself, not about the company that made your clothes. Wear a T-shirt and jeans, wear cargo pants, wear whatever you want because you're supposed to be making a statement about who you are, not who a company wants you to be.
I grew up in OC, So Cal, and bailed out to a rural mountain area some years ago. I wear jeans, tshirts, hoodies/jackets and either work boots or flip flops on an average day (I'll still dress up for weddings and other events that call for it). Every time I go back down there to visit, My brother and best friend feel the need to try to dress me like a damn ken doll before we can go anywhere, to no avail and it turns into an idiotic argument every time. I've repeatedly explained that I wear what's confortable, and I don't give two shits what some uppity muppets think of me based on how i'm dressed. I'm already married, have a great job, and make good money, so I'm not out to impress anyone.
For the record, all of my clothes are always clean and in good repair, I just dress extremely casual and confortable. I think these guys are just so would up in the rat race that they have trouble imagining life otherwise.
