姿色

姿色 specifically refers to a woman's physical attractiveness, often with a slightly old-fashioned or literary tone. Common collocations: 颇有姿色 (rather good-looking), 略有姿色 (passably attractive), 有几分姿色 (has some looks). For modern neutral "beautiful," use 漂亮 or 美.

Slightly bookish - fine in narration but feels detached or evaluating in conversation. Saying 她很有姿色 about a friend can sound like you're sizing her up.
