Out of curiousity, which barn do you ride with? I have been to a few TSSA shows, and you do not braid for them. You are lucky if everyone clips the horse (I'm talking bridle path, ears, fetlocks, not body clipping). For the Centex shows, the only time I have seen a horse braided is in the Hunter Breeding class at the Summer Circuit Rated shows, not even at the year end Medal Championships. Trust me, it took me a long time to get used to it. My trainer moved her from CA a couple of years a go and showed up to a Centex show braided and everyone looked at her like she was crazy. Now she only braids for A shows (I'm not sure about the B shows), and Centex is at the highest rated as a C with often times no rating.
Here is a website with photos from numerous TSSA and Centex shows. Take a look around to get an idea. And best of luck to you this year! The shows aren't very formal, but they can still be fun Main Gallery
