Trying to figure out a real minimalist lifestyle in wardrobe and minimize my consumption

I have always tried to keep my wardrobe minimal, with only items that I need, thinking that I was being a “minimalist”. I thought I was being efficient by grabbing those cheap 5-packs of basic tees from Amazon or ASOS and other fast fashion brands, which I end up having to buy again in a few months because their shape is impossible to keep.

They were so thin that they’d lose their shape after several washes with saggy neckline/ collar, which makes me look somewhat unprofessional at work.

This is a cycle that i realized I must stop. I tried MUJI first, I love their aesthetic, especially their minimalist approach to design using all natural fabric. Their cotton shirts look so good on their website. Boxy fit, but I still love them.

Uniqlo is another good choice actually. So I have a few of their tops as just my go to. Product wise, they are great. I also wanted to look into something a bit more environmentally friendly.

Picked up 3 bio-cotton tops from some OGL basics recently. The fabric is a bit heavier and has that "sandwashed" density, keeps its shape for the whole day. Been through the wash a bunch of times, holding up pretty well so far.

I'm starting to think that maybe three shirts that actually last can help me drastically reduce my consumption than cycling through cheap ones and wasting them after a few use? But I'm honestly not sure if I'm just rationalizing spending more upfront.
