In 1990, Equestrian's founder wore aerobic exercise pants to go horseback riding. Noting the comfort and fit, she began working with a seamstress to revolutionize riding breeches. These pants became the newest success in the equestrian world and were dubbed the “Miracle Pant” for their slimming effect and remarkable quality. In 2004, the senior assistant designer bought the company and streamlined processes, expanding the line beyond the equestrian realm.
