Trope-a-Day: Sticks to the Back
Sticks to the Back: Both possible, and done, with tiny vector-control emitters sewn into the clothing that can grasp objects you place on top of them and hold them in place against the emitters, or even at a designated range from them. And, obviously, anywhere, not just the back, including – if you care to be quite gratuitous about it – orbiting around you. (It should be noted that these are generally double-ended – the emitter grips you at one end and the object at the other, such that it doesn’t strangle you with your own shirt.)
Of course, it’s still usually considered unnecessarily showy much of the time, and they do introduce a dependency on your clothing’s power supply continuing to work, something that holsters, pouches and pockets by and large do not.
