Are there eco-friendly options available for casual tops?

I visited a clothing shop to find eco-friendly tops two days ago. I wanted something sustainable and soft. I also wanted safe materials. But when I checked the tops I felt disappointed. Most were not eco-friendly. Some looked weak and cheap. I could not trust them. I could not decide confidently.

Then I visited another shop in the same area. Some tops looked better but were expensive. Some were affordable but not sustainable. Some seemed perfect at first but material was unclear. I remembered I used a top before that lost quality quickly. That made me hesitate even more.

To check more variety and options while scrolling many online marketplaces including alibaba I found many eco tops. Some looked sustainable and soft. Some were simple and low price. Some had better materials and durability. There were many options available. This made me excited but also confused again.

it feels that I go out of mind when I have huge number of options. Now I am thinking should I trust eco products online or local stores for real sustainability? What would you do in my place?
