Why does “sustainable clothing” so often feel… disappointing?

I’ve been trying to switch to more sustainable fabrics lately, and the experience has been surprisingly inconsistent. A lot of brands position themselves as “eco-friendly” or “ethical,” but when I actually try the products:

• Some feel oddly synthetic, even when they’re plant-based
• Some wrinkle too easily or lose structure after a few wears
• Some are priced at a premium without a clear difference in feel or performance

It made me question something that “sustainable” seems to focus more on how something is made, not how it actually feels or holds up in real use. So I’m trying to understand this better:

• Which fabrics have actually held up well for you over time?
• Are there materials you actively trust or avoid?
• Is there any reliable way to judge quality before buying?

Curious to hear real experiences, good or bad.
