Trope-a-Day: Waistcoat of Style
Waistcoat Of Style: Played straight, for both sexes (cut appropriately differently). The Empire is a “thingist” culture that particularly enjoys its little pocket gadgets for this and that and the other thing, so obviously, you need a garment specially adapted for keeping them in, starting with your fob… terminal.
(And you generally can’t use your trouser pockets, because your weapon belt – and attached sidearm and blade(s) – gets in the way.)
