Describes a person, especially a woman, or an object that is slender, elegant, and tasteful. Often used in literary or formal contexts. Functions as a taru-adjective, commonly appearing as 楚々とした or 楚々と.

優雅 is a more common word for elegance and grace, used in everyday language, while 楚々 is literary and emphasizes a slender, neat refinement.
清楚 also means neat and clean, often describing a person's appearance or attire, but 楚々 carries a stronger nuance of delicate, willowy grace.
The exact derivation is uncertain. The kanji 楚 originally refers to a thorny bush or a switch, but in Japanese it is used in this compound to convey a sense of slender elegance, likely through literary association.
