@sinituulia i actually almost always wear vest-like jacketpulloverthing (i like to be able to just open the zipper for optimal temperature management :) ) but having a phone in its pocket is annoying, modern phones are just too large and solid to carry in a pocket that can "flap about".
I have to admit It's nice to have a computer in your pocket at all times, but fashion needs to go with the times and offer phone pockets, like the small pockets that evolved in suits to carry pocket watches.
