I don't know if it's technically a cravat, it's just a ... neck ... scarf ... thingy. Everybody was wearin' 'em. In olden days.* Neckerchief? Useful thing. Keeps your neck warm in the winter and cool in the summer if you damp it down, and hides the stitches if you're living-impaired with past head-attachment issues. And everyone ... everyone looks better in a cravat (or neckcloth of your choice). That's just the way it is.

Silly, everyone knows it's pronounced cor-SAAAY... 'S like ... French.
