"Rainbows End" by Vernor Vinge has all the younger people (and those grown-ups who are hip) "wearing". Their clothes are (in some unspecified way) I/O devices, so that they learn from quite young how to communicate and control things through imperceptible movements. Teaching her grandfather how to "wear" is part of how the main protagonist gets caught up in the events of the novel. The novel is pretty vague about how much bandwidth is involved, but the convenience is the thing - you are wearing clothes all the time (or at least during waking hours if you prefer to sleep naked) and so if you've learned it then replying "Yes!" to a friend's question about whether you want them to save you some apple pie becomes no harder than nodding is, except it works at a distance.
