Aha one more question. White breeches, or light ones?
I just finished reading another thread about this very thing...I believe it was on this first page of English Riding/"Dressage", and I believe the OP was wondering about bits for intro/training level showing.
I believe (though please check the thread because I don't want to misquote) that a few people said that a dark colored coat, such as navy blue would be fine, and that light colored, though not necessarily white, breeches should be acceptable, as would be a non-dressage english saddle.
The take home message I got from that other thread was that at the early levels, the judges are primarily interested in the basics having been properly trained regarding the horse, and ensuring that it is going willingly. Naturally there are rules; (it's literally been like 100 years since I've been to ANY SORT of horse show, let alone PARTICIPATED! This info I am relaying is all from the other thread I read therefore I really hope I am relaying appropriately!) and the rules will encorporate all the same things as at any show, such as acceptable/"legal" bits, clothing in general, the rules of the test, and various things like that, but it seems
they are more relaxed about preciseness of clothing than at the higher levels. Of course you would want to appear well-put together and neat/tidy, along with your horse (sorry, I know this goes without saying, but I over-write!) :eye roll:
I would read through the rules of the particular show you are interested in and I would GUESS the information you seek will be included in the forms?
Good luck to you! Have FUN!!
