Adding pockets costs next to nothing.

You think this is some overlooked thing that the clothing industry never considered? That this is some secret niche that just hasn’t been filled? They don’t sell. If they did, then there would be brands or clothing lines with pockets, and marked up for the piddly cost of the manufacturing expense.

That has NEVER HAPPENED. It’s not because the manufacturing can’t be priced adequately despite high consumer demand, it’s because for all the shouting at clouds, women, in general as a consumer demographic, do not buy pants with pockets.
