Gibson girl (n.)

"woman considered stylish at the turn of the 20th century," 1894, named for U.S. artist and illustrator Charles Dana Gibson (1867-1944), whose main model was his wife, Irene Langhorne (1873-1956). The Gibson cocktail (gin, vermouth, and a pearl onion) is attested by 1914, in some stories ascribed to him but the origin of the term is unknown.

"She looks like a Gibson girl" is not an uncommon saying; and to look like a Gibson girl, is not without its merits. Although our artist has expressed in his drawings disapproval of women usurping the spheres of men, his girls suggest intellectuality. He has none of the doll-like inanely pretty faces which artists used to give women in olden days. His girls look as if they would have opinions of their own and would act with discrimination in the affairs of life. They are tall and graceful and although not in the least like fashion plates, their clothes are becoming and fit perfectly. [National Magazine, May 1898]
