As an exercise, go to any mall or shopping center and try to find a pair of women's jeans that meet the following criteria:
1. Decent quality material, is not deliberately pre-destroyed 2. Functional pockets, but not outlandish 90s style cargo pockets 3. Cut with a straight lower leg, not flared or tapered "skinny", and a proportional leg overall, not extra-wide or skinny 4. A waist size that doesn't assume the wearer is an athlete with a flat stomach (remember, women's pants are sized by number, not by waist x length), even in a "curvy" fit 5. Is not purpose-designed hiking gear
If you can find anything meeting all 5 criteria, I will pay you a $50 finder's fee and consider booking a trip to visit your fair city, because my wife would be thrilled to know they exist.
Revealed preference only ever makes sense when interpreted as preference among available options, not preference among all possible options.
> Evidence suggests that any demand is a vocal minority
The demand for any one individual improvement is probably a relatively vocal minority. There are so many busted messed up attributes about women's clothing that it's hard to choose any one of them to be vocal about. So the overall effect is diluted.
That, and, a lot of women are probably just used to carrying their stuff in a handbag and don't even realize that decent pockets could be an option. Likewise for the unnecessary forced selection between super skinny and super wide jeans.
