Despite the meaning "traditional clothes," "costume" may be considered pejorative by some cultures as a reference to their own traditional dress, owing to interference from the sense "fancy dress, disguise" (such as if their traditional dress has often been appropriated by others as fancy dress). For example, many Indigenous North Americans disfavor the term "costume" to refer to their traditional and ritual garments and prefer the term regalia.
- costume party
costume (third-person singular simple present costumes, present participle costuming, simple past and past participle costumed)
- To dress or adorn with a costume or appropriate garb.
