>>262883nta from before, but kek, I think that's the whole thing behind pattern making, I'm at school for it right now and get to know all the basics, but if the "market" doesn't want high waist jeans, you won't design high waist jeans and if you only need to change the placement for a pocket about 5 cm, then you do it.
As you are designing jeans, has the fabric choice changed? In Germany it seems like people start to prefer fabric without elastane in it, just pure cotton, did you notice that, too, or is that just something going around richer people trying to be woke and safe the environment.
