A high, flared, turned-up collar commonly associated with characters with mystical powers. Often worn by Wizards, Psychics, and vampires. Frequently found as part of a Cloak (and thus does not count as Collar for Danbooru's tagging purposes). May often be decorated with occult symbols, and colored differently from the outside surface of the cloak.
Avoid tagging High Collar unless the 'collar' also noticeably covers the neck.
