The film's the story of a high-spirited girl named Gigi, and her journey into womanhood and finding love. Pretty straightforward, right? We could speculate that since Gigi is her childhood nickname (short for Gilberte) the title's emphasizing her girlish qualities that make Gaston fall for her in the first place—her energy, unpretentiousness, and playfulness. Gilberte would be just like all the other courtesans; Gigi stays true to herself.
