As far as I can tell, this is a key driver of why the EU implemented anti-waste provisions for clothing starting in a couple years: because retailers will just order arbitrary amounts of clothes and shred (!) whatever is unsold, which since they made their profit, doesn’t cost them anything and saturates the planet in formerly-wearable clothes that have been destroyed out of wasteful sloppiness. If they actually had to put in effort to design production runs — or else see their clothes sold at the bargain store — then they may well start acting less “why bother, we got our money, next”. One hopes, anyways.
