Yes, you can wear individual styles of jeans while riding the horse. Some recommendations include long jeans, pants, jodhpurs, and breeches. Avoid using shorts or inner leg pants as the seams can chafe. It would help if you paired jeans with long boots with heels so that the feet do not get caught in the stirrups in case of a fall. Also, make sure it is made of soft yet durable material for jeans, and the seams are not hash on your legs.
