Auguste Racinet. The Costume History by Françoise Tétart-Vittu.
Racinet's Costume History is an invaluable reference for students, designers, artists, illustrators, and historians; and a rich source of inspiration for anyone with an interest in clothing and style. Originally published in France between 1876 and 1888, Auguste Racinet’s Le Costume historique was in its day the most wide-ranging and incisive study of clothing ever attempted.
