Skeletal Hand Bun Slide

A low bun is the easiest hairstyle to get right and the hardest one to make look like a decision. This clips flat across the back of it - one skeletal hand, fingers splayed and curling in slightly, long enough to span the whole bun. Gunmetal reads almost black indoors; silver picks up whatever light is in the room. It lies parallel to the head rather than standing off it, so it survives leaning back in a chair.
