Yes- because it is a schooling show. The schooling shows here in CA are quite competative but it sounds like yours is low key so you should be good. Do you have black boots and black half chaps? If so that would be best- oh and wear a black belt... white shirts are best too.. good luck and post some pics so we can see how it goes!
I've got black boots, and am going to get some black half chaps.. do they HAVE to be leather ones? Because its not being counted on appearance (well it probably is a bit!) its more of what the horse can do and that.. because it will be summer, do you think that a white shirt, beige/tan breeches, black boots + half chaps, black gloves and obviously a hat? What would I need to do/get for the Horse (ie. Saddlecloth etc)? Sorry for all the questions!
Black gloves and belt
Black boots and half chaps (i don't know the level that they are holding you to so whatever you think)
Black helmet- preferably with the velvet covering
Pull your hair up under your helmet
If you have a pin that you can put on your rat catcher (the piece of cloth that goes around your neck)
Matching english tack
A saddle pad(one that is the same shape as the saddle)
Bathe your horse
All the mane the the right side (if possible)
Clean hooves with some polish (if you have it)
That's all I can think of- I am in a hurry so if you have more questions let me know :)
Laura, if you don't mind me asking, where are you from? Showing is very different in the US as it is to say, Australia, where I live. Attire is very different, what a lot of people wear to shows in the US is not acceptable here.
That was a good question. I should have known something was up when you called a helmet a "hat". Well this could change everything then and I don't want to give you incorrect advice. I think maybe your best bet would be to contact the organization hosting the show and check their rules and guidelines.
I would guess in England they are a little more 'proper' (for lack of a better word, lol!) I'm not sure that a polo shirt would do it. I would definitely agree with contacting the organization. Even a bit of googling could help. I found a ton of stuff on presentation and workouts for english hunter under saddle classes a little while ago.
