Not wearing a necktie, often referring to a casual style of dress.

Tieless is formed from "tie" (from Old English "tīe", meaning a cord or strap) and "-less" (meaning without). The word "tieless" means without a tie, typically referring to clothing that does not include a necktie.
Think of being 'without' ('-less') a 'cord' or 'strap' ('tie') — that's what tieless means.
