A somewhat dated or literary term for a person overly concerned with appearance and vanity, especially in dress or manner. Often used in a critical or mocking tone.
He is a vain person, always chasing the latest trends.
I'm fed up with that show-off attitude.
Refers to a stylish or dandy man, often with a positive or neutral nuance, while 見栄坊 is more critical.
Compound of 見栄 (みえ, 'vanity, showiness') and 坊 (ぼう, 'boy, person'), literally 'vanity person'. The exact origin is uncertain, but it likely emerged as a colloquial or literary term in the Edo or Meiji period.
