Women's pants should have cargo pockets big enough to fit any grandmother's purse. If some of my pants pockets can go up to my elbows (not even exaggerating, it's an embarrassing pain to fish my keys out of those pockets), then women should be able to lose their wristwatch in a cavernous pocket.

Anecdote: Sometimes my wife carries a pair of ankle-high socks in her purse, in case we're gonna have to take our shoes off or whatever. This sometimes requires reorganizing her bag. When she's told me to take an extra pair of socks, of which I only have knee-high compression socks, I just match a pair, fold them, and stick them in one of my four available pockets on any of my pants. I do not have a single set of pants incapable of holding a week's worth of knee-high compression socks.
