A paletot is a type of topcoat.
The name is French, but etymologically derived from the Middle English word paltok, meaning a kind of jacket.
[1] Historically, it was a semi-fitted to fitted coat, double-breasted or single-breasted, the front sometimes fastened by a fly, with or without pleats, and with or without pockets.
A modern paletot is a classic business overcoat, usually double-breasted with a 6×2 button arrangement, the top buttons placed wider apart and not fastened, with peaked lapels, a flat back and no belt.
A paletot is often made of flannel or tweed in charcoal or navy blue.
