Canuck with several ex-military friends. Someone in mufti is a soldier wearing civvies. Among my friends, it's colloquially extended to mean any kind of dress-down (e.g. casual Fridays at businesses), but not widely used among people who've never been in the services. "Mufti day" means nothing to me.
