as its a local show you may just have to walk, trot and canter round together, then youl get pulled in, do your individual show which will envolve a change of rein and trot and canter on both reins.
I dont think you'l have to strip the horse for a local show!!
nothing fancy, keep it plain, simple and proffessional(tack wise) you can put as much showing products on as you like lol!!
