At this very moment, perhaps, Toad is busy arraying himself in those singularly hideous habiliments so dear to him, which transform him from a (comparatively) good-looking Toad into an Object which throws any decent-minded animal that comes across it into a violent fit.

It deepened; it purified. It lost its previous comedic habiliments, its air of shtick, and became unadulterated, lethal, pure despair.
-- Jeffrey Eugenides, The Marriage Plot, 2011
Habiliment comes from the French word of the same spelling. It's from the root habiller meaning "to dress."
