Zippered pockets on jackets: the first fashion trend necessitated by androids. As a default outfit, androids almost always wear some kind of micro textile, synthetic pants. Carrying a bunch of pocket cargo is just going to get in the way of all that precision bioengineering. Some tastemaker types decide they like the looks of that, so they copy the androids, who are built copying us as close as possible in the first place. Anyway, with all these skintight, seamless pants, they had to put pockets somewhere else.
