コスチューム

こすちゅーむ
noun
costume (for a character, performance, or themed outfit)
1. costume; outfit (for a character, performance, or theme)
A set of clothing put on to represent a character, role, or specific setting — for example, at a play, concert, cosplay event, or Halloween party. Borrowed from English "costume."
かわいいコスチュームを()った。
I bought a cute costume.
ハロウィンのコスチュームを準備(じゅんび)している。
I'm getting a Halloween costume ready.
舞台(ぶたい)()るコスチュームは、デザイナーが(ひと)つずつ手作(てづく)りしている。
The costumes worn on stage are handmade one by one by a designer.
()きなアニメのキャラクターのコスチュームを()て、イベントに参加(さんか)した。
I wore the costume of my favorite anime character and went to the event.

A loanword from English "costume." In Japanese it refers almost exclusively to "dress-up clothing" — the outfit for a character, theatrical role, concert, or themed party. It does not cover ordinary "clothes" (for which (ふく) or 洋服(ようふく) are used) or traditional national dress (for which 民族(みんぞく)衣装(いしょう) is the usual word).

COMMON COLLOCATIONS:

  • コスチュームを()る: to put on a costume
  • コスチュームを(つく)る: to make a costume
  • アイドルのコスチューム: an idol's stage costume
  • ハロウィンのコスチューム: a Halloween costume
  • キャラクターのコスチューム: a character's costume

SIMILAR WORDS:

  • 衣装(いしょう): costume; outfit — the native Japanese word. Common for stage, dance, film, and traditional clothing (e.g., 舞台(ぶたい)衣装(いしょう), stage costume). Broader and slightly more formal than コスチューム.
  • コスプレ: cosplay — a further shortening used specifically for dressing up as anime, game, or manga characters. The outfits worn for it are called コスプレ(こすぷれ)衣装(いしょう) or コスプレ(よう)のコスチューム.
  • ユニフォーム: uniform — standardized work or sports clothing; never called コスチューム.

USAGE:
You will encounter コスチューム most often in the worlds of theater, idol performances, Halloween, and cosplay. In more formal or traditional contexts — historical drama wardrobe, ballet, kabuki — the native word 衣装(いしょう) is preferred. The two overlap but are not fully interchangeable.
