Is it impossible to find clothing that is sustainable, affordable and cute? Does that exist?

I need to buy new clothes and I’m finding it nearly impossible to do it sustainably, affordable and still think the clothes are nice. I find you can tick one or two boxes but never all 3.

Some background on why I’m saying I need clothes and not just I would like them:

I’m not completely broke but don’t have a huge budget for clothes atm.

I don’t have a huge amount of clothes to begin with (used to work full time in a uniform, play sports etc so what I wear in my free time isn’t suitable).

My body has changed quite a bit in the last year or so, not a lot of my clothes are still wearable (not replacing anything that still is wearable). Things like pants or jeans I’m very low on.

I try to be as sustainable as possible but lots of sustainable clothing brands are very expensive or might have good basics but are kind of boring. I want to feel comfortable and confident, I want my outfit to have some personality.

I try second hand/vintage shops and things like Vinted but find it very hard to get everyday items, not like statement pieces, finding specific sizes is hard, and there’s also lots of shein and other low quality fast fashion that I’m trying to avoid.

Is there anyway to not sacrifice on either sustainability, affordability and style? Is there anyway to work around this or ways to let go of one of these things as ethically as possible? Please help I want to be sustainable but I also have to be realistic ❤️
