This word stems from the French “accoutrer,” originally from the Old French “acoustrer,” which comes from the Latin “ad,” meaning “to, at,” and “cousture,” meaning “sewing.” You might recognize a similar clothing word that shares this Latin root: “costume.” In English, “accouter” is sometimes spelled similarly to the French version, as “accoutre.” Both spellings mean “to clothe or equip something noticeable or impressive.” You wouldn’t describe getting dressed in basic jeans and a T-shirt as accoutering yourself, but if you put on your fanciest duds (or a costume), that fits the bill. A related word, “accoutrement,” denotes accessories and additional clothing items beyond a basic outfit.
