Why is Pact such trash?

I've been trying to buy organic and natural fibers, and ordered several summer pieces from Pact on sale.

Unfortunately they arrived today and the quality is absolute trash. The knit dresses are so thin I am not comfortable wearing them out in public. I may wear them around the house or as sleepwear but I don't normally buy knit sleepwear (or spend so much!) Literally the $9.99 knit cotton dresses at Walmart are thicker better quality than these.

Sustainable fashion isn't sustainable if it only lasts 3 washes. What is the point of sourcing organic cotton and fair labor if you are going to waste it making junk?
