I understand that fast fashion brands aggressively cut costs to mass-produce as much trendy clothing as possible, so I'm not surprised when I see a low quality fast fashion item. However, what is surprising to me is that the clothes actually significantly vary in quality, even within the same brand. So in a fast fashion store you may find a garment made from the worst synthetic blend ever, with messy stitches that'll definitely tear apart after a single wash cycle. And then on the same shelf there'll be a fairly well-made item, from a sturdy natural fabric, with very precise seams and details. And oftentimes, those two garments will be sold at the same price point.

How does this happen? Do the fast fashion brands just randomly decide to spend more money on some of their clothes? Why don't they just make all of their clothes equally low-quality to cut costs, or make them all a bit better to increase satisfaction? How can a single company have such different quality standards for different products?
