Manga and anime have boosted the popularity of the term 'butler' since 2010. In the 90s to early 2000s, the image of a butler was somewhat elderly, but recently, characters like Sebastian from the manga "Black Butler" (黒執事) have given butlers a stylish image. However, few people have actual interactions with butlers. Do they really dress as they do in manga? Are there detailed rules for their attire? Bell from the
All Japan Butler Association (全日本執事協会) answered my endless curiosity with great care.
