Propriety, decorum, or the conventions of polite society; what is considered appropriate behavior or dress (French loanword, formal/archaic).
From French 'convenance,' derived from Latin 'conveniens' (fitting, agreeable), based on 'convenire' (to come together, to suit). Borrowed into English in the 17th-18th centuries for matters of etiquette.
French aristocrats obsessed over 'convenance'—it wasn't enough to be honest; you had to be *appropriately* dressed, speak in the right tones, and demonstrate you understood your place in society's elaborate dance!
