The term "lady of evening" is often used to describe a woman of elegance and sophistication. However, there are many other synonyms that can be used to depict this type of woman. Some of these include "dame of the night," "nighttime lady," "evening mistress," and "dusk queen." These synonyms all suggest a sense of glamour, poise, and refinement. They also imply a woman who is comfortable in the evening and nighttime environments, and who exudes an aura of grace and beauty. Ultimately, though, the choice of synonym will depend on the context and tone of the piece of writing.
