Surely, if seamstresses agree, then selling women’s clothes with bigger/more pockets is not a novel idea.
And making clothes with bigger/more pockets does not require a high barrier to entry, the technology has been there for decades.
And profit margins on clothes are tiny, so it stands to reason that sellers would be looking for any edge they can get to sell more clothes and/or at a higher price.
If you agree with the above, then there are two options:
1) for decades, people whose livelihood is selling clothes have missed an obvious opportunity to earn more money
2) people whose livelihood is selling clothes have not been able to succeed in selling women’s clothes with bigger/more pockets
If option 1, then someone needs to jump into this business. I sympathize with my wife and daughter who also complain about the lack and size of pockets, but I am not sure how to square that with the above parameters. Maybe it is an under-explored business opportunity, but it is so low barrier to entry that it seems unbelievable that the answer is not sufficient lack of demand (option 2).
