sylphlike
Like a sprite
Sylphlike describes a slender, graceful figure, especially of a woman—light and airy in movement or build: a sylphlike dancer, her sylphlike frame.
The word evokes the delicacy of a sylph, an imaginary spirit of the air.
It's literary and somewhat old-fashioned, carrying connotations of ethereal beauty rather than mere thinness.
