Do we really need to plastic in our clothes ?

I am thinking to start my own lifestyle apparel brand I really want to work on natural fibers but lill confuse how can I integrate all natural fibers into our daily life . Unconsciously and consciously synthetic and polyester fibers is now every wear in daily lifestyle .
At the same time, I understand that synthetics exist for a reason—they can add stretch, durability, quick drying and help keep prices lower.
But Iam not a person who love wearing it ,I don’t how many people do love wearing them in Indian weather condition. I can’t tolerate sweating all the time when ever we are out and discomfort.
So Iam curious
Want suggestion from you guys do you all feel the same , should I go head with this plan of building plant based fiber lifestyle brand or not ?

Would you actually prefer everyday clothing made mostly from natural fibres like cotton, bamboo, linen, hemp, etc.?
And more importantly, would you buy from a brand that actively tries to reduce polyester and synthetic fibres, even if the products cost slightly more?
Trying to understand whether this is a real problem people care about, or mostly just my personal preference.
