The convention of formal riding habits for women came into fashion during the 17th century. Riding habits were designed to be fashionable, though not always practical. Before the advent of riding habits, women rode in everyday dress. While horsewomen generally rode sidesaddle (for reasons of fashion and modesty), it is difficult to discern what manner of riding Beauty prefers, though it might be inferred from her choice of a divided skirt that she rides astride.
