Pertaining to habiliments or the wearing of clothes; relating to dress and clothing.
From habiliment plus -ary (relating to). This is an even more elaborate form than habilimental, creating a super-formal adjective for clothing-related matters.
English loves creating synonyms by adding different suffixes—'habilimental' and 'habilimentary' mean almost the same thing but sound slightly different. It's like the language is showing off its Latin and French roots all at once.
