“Little Lord Fauntleroy was created by author Frances Hodgson Burnett in 1886, but it was the illustrations by Reginald Birch that sealed the Fauntleroy look. The velvet breeches and white lace collar worn by Cedric in the novel were also worn by the author’s two sons.”
The boy in the picture was Burnett’s own son, Vivian, wearing one of the two Little Lord Fauntleroy suits that were made by his mother for him;
It’s not unusual to see young boys dressed in Fauntleroy fashion in classical shoujo manga. One of the most famous Fauntleroy-fashioned boy is Allan Twilight from Hagio Moto’s “Poe no ichizoku”, and such characters were a frequent motif in the works of Uchida Yoshimi, among other great authors.
