Typical equitation class apparel includes a show jacket, white show shirt, tan colored pants, belt,polished tall boots, & a clean black helmet(Charles Owens are most often seen). Make sure all of your tack is very clean, if your horse wears splint or ankle boots, make sure they're clean leather(or leather/sheepskin) boots. Generally, there is many rollbacks that you want to make the tightest turn that you can do cleanly. Equitation is suppose to be based on your position & cleanliness of getting around the course, although today it is getting closer to being based more closely to a hunter course(which makes me mad!) & less about your true position. Still make sure you have a tight leg & quiet, still body.
