I'm pretty sure when machine-made cloth started in the 1700s or so, people complained its quality was worse than handmade cloth by experts.
The trend to fast fashion and now ultra-fast-fashion, driven by ever-increasing marketing pressure to buy the latest, constantly-changing trends, despite expose after expose showing its huge environmental impact, shows that education wouldn't be enough.
How would one even evaluate cloth material quality online? We know the ads for a Hardee McWopper Burger show some amazing looking hamburgers made using exactly the same ingredients as sold by the stores; a look achieved by expert designers and photographers. I expect the exemplar used for online marketing will be equally ... optimized .. for appearance.
Those are factors for why I don't do online clothes shopping.
