Tan breeches. Tall boots are fine if you get them. I would wear a hair net and try to put your hair ALL up in your helmet. I think the baby blue polo would look great, or a pastel pink, or pastel yellow. Don't worry about the stitching on your saddle changing color. It doesn that over time with the wear and tear. Use something called "Never Dull" on your stirrup irons, then buff them with a cloth. If you don't have the never dull, then you can just scrob with a sponge and soap and then buff. Good luck! Have fun!
