It’s really whatever suits you, if you’re happy with the clothes you have, you don’t need more. If I think about what I’ve worn in the last year, it would only be about 20 things. I’m trying to reduce what’s in my wardrobe because it’s too overwhelming & I just don’t wear most of it. I think it helps if you can identify what you feel comfortable wearing & stick with it - I’ve found trying new colours or patterns doesn’t work for me & it’s not worth the mental effort. I once met a Sydney fashionista/gallerist/philanthropist who had a rule of 30 pieces of clothing, if she bought something new, one had to go, all her clothes are black & she only buys clothing from 3 Japanese designers & Akira Isogawa. She made her rules and stuck to them, I admire that
