For women: it may be worth your while checking out Project333. I have searched for a respective project for men, but haven't found something similar/worthy.
When I finished listening to the Minimalists podcast (first 120 episodes) for the second time I was already immersed in minimalism. I donated 90% of my clothes, I now have 5 t-shirts, 4 sweaters, 2 jeans, 10 pairs of socks, 2 pairs of shoes, and some snow/skiing related accessories (hoods, etc.)
I also have "office clothes" which I don't count as clothes, I treat them as a uniform, when not in the office, they don't exist for me (and Coronavirus-->remote working was a great 'gift' for me on this area)(I hope the deaths stop and we continue the WFH).
I see fashion as a "subscription" scheme. You spend £€¥$, you get clothes and after X seasons you need to spend another load of £€¥$ to renew your "trendy-ness".
I can never forget that in the term "fashion VICTIM" the word that sticks with YOU is the word "victim".
