woman with an attractive aura; woman who is not classically beautiful but has great charm
Colloquial term for a woman whose appeal comes from her overall atmosphere, personality, or style rather than conventional physical beauty. Often used positively.
She's a woman with a wonderful aura; being with her is very calming.
あの人はいわゆる雰囲気美人だよね。
That person is what you'd call attractive in a non-traditional way, isn't she.
Compound of 雰囲気 (atmosphere, mood) and 美人 (beautiful woman). The exact origin is uncertain, but it likely emerged in colloquial Japanese to describe a type of attractiveness not captured by traditional beauty standards.
