Horseback riding question!?

ok, im going to this ranch called ridin' hy in new york sunday and u can ride horses and stuff. i ride english, and at the ranch the saddles are western. im gonna bring my IRH helmet and my Ariat boots (which are both english), but i dont know if i should wear my half chaps and my breeches, because it is western. i feel more comfortable in that then riding in jeans, but what do you think?
