My SIL doesn’t want pockets, but she is wealthy and into style. I think some of the women who don’t want pockets are into style and/or looking wealthy enough to not need pockets.
Women who are pragmatic want pockets.
I’ve been ripping open pockets and sewing more fabric onto them making them big.
If you own a sewing machine I suggest if any of those clothes have mini pockets ripping the seams and adding fabric to make a big pocket. Help her take back her power!
