Costumery → The word is derived from 'costume' (from French *costume*, meaning a style of dress or clothing) and the suffix '-ery' (meaning a place associated with or a collection of). Thus, 'costumery' refers to a place or collection related to costumes or clothing.
Think of 'costume' as a style of dress and '-ery' indicating a collection or place, which helps you remember that 'costumery' is about a collection of costumes.
