I can't recommend a brand, but I understand your pain. My mare and I were both originally western, and we learned english together- well, I was learning while my mare was like "Trot faster? YES, FINALLY!"- I declared it a new discipline and dubbed it "Ghetto English" because after a while I realized since I wasn't planning on competing, I could just wear straight leg jeans and half chaps and call it good.
I've ditched the half chaps now. It confuses people to see a girl in blue jeans get on a cutting bred quarter horse with english tack and then go on to hop over a couple jumps, but we're having fun and that's all that matters
Plus my instructor couldn't care less. As far as she was concerned, it wasn't what you wore but the way you rode that declared your discipline.
