Swinging Sweetie Gil Elvgren (1914-1980)

The picture has something of this: woman, fashion, indoors, dancing, girl, glamour, exercise, sexy, young, brunette, music, dancer, ballet, action energy, wear, pretty, beautiful, sitting.
Perhaps it’s a painting of a woman in a white dress swinging on a rope with a green hat on her head and green shoes on her feet and a yellow background.
