through demand at first. clothes designers are hopefully going to demand smaller batches to avoid getting punished for overproducing. but if that doesn't work, then yes, maybe regulation is necessary. tricky though because manufacturing is often outside of the EU.

overproduction needs to be made more uneconomical than smaller batches. if that is really the issue. i really doubt that large batches of production are actually the problem here.

How much longer do you wait to see if demand solves it? It hasn't. The problem has gotten worse
