Other than a couple of sports shorts & t-shirts and some technical 'outdoor' gear I've not bought any clothes in years tbh. Covid means I don't even have to worry about work clothes getting worn out / scruffy.
Tbf part of the reason I've been able to do that is that I've built up lots of clothes over the years and don't throw much out. I had a massive number of socks and underpants so despite throwing a few undies out and getting rid of socks when they get holes in I've still got a drawer full.
A lot of my wardrobe is getting a bit worn now, but honestly I just don't like spending money on clothes and can use the environmental excuse too
. I'm not particularly fashionable and my friends and gf aren't too image focused so Ivve not really got any external pressure to get me clothes either.
Eventually stuff gets old enough that it's too scruffy even for me and it goes in the bin / charity bag (even if it's too scruffy for them to actually sell on they can make rags from it for wiping stuff down in workshops etc I am told).
