I can’t say how many times I’ve tried to stick my phone into the front pocket of my jeans, only to have the pocket be, literally, two or three inches deep — nowhere near big enough to fit my phone.
There’s no point to having a pocket that small. The only thing I can use it for is to stash spare coins, which isn’t even a pocket’s proper use. And don’t get me started on fake pockets.
The only pockets that function decently on girls’ pants are the back ones, and although they usually work, I find them highly uncomfortable. When I put my phone or wallet in my back pocket, I can’t sit down properly, and often, it isn’t even large enough to hold my phone anyway. But even if I put my phone or wallet there, I run the risk of it falling out or being stolen without me ever knowing it even disappeared.
