Day is taller than most women, but not wildly so. Part of it is simply her posture. She has the rigid bearing and squared shoulders of someone who's spent time in uniform. The well-maintained clothing, too. Her hair is dark, kept neatly trimmed into the sort of cut that would pass muster. Her choice in outfits runs toward the simple. Muted greys and matte blacks are common.

With dusky, almost caramel skin and a fit physique, Day looks like she has spent at least some of her life under a sun. Or at least in a place lit as if it had one.
