Does that shiny new car come with all the bells and whistles? Then it has plenty of accoutrements, or accessories.
Say accoutrement with a French accent and you'll be referring to an outfit — a particularly bizarre outfit. But when we borrowed the word from France, it evolved to refer to any kind of trappings or extras, especially clothing accessories. So an accoutrement can be anything from a belt or bangles, to extra cup holders and heated bucket seats.
