IMO, purple isn't the best color for a bay. You colors are fine for gaming but there's better for pleasure. The red blouse would look awesome with black chaps and a white hat to show off your pretty face. I would opt for a black pad or pad cover. There are no rules regarding silver. A little silver on the bridle would help draw attention to the attractive head. Think about how you can enhance the horse's attributes. If you use the brown bridle, push the brow band up toward the base of her ears as it will enhance her eyes. Now, you are judged the moment you begin entering the gate, not later. Before you get to the gate allow the horse ahead to get a good horse length ahead of you. As you enter the gate, look like both you and the horse just arrived from the dry cleaners, no bit goobers, no dust on your boots and smile wamly to the judge to acknowledge him/her. One gal who often won pleasure lost out one day because as her horse was entering the gate it stopped and took a step back then came forward. Bad first impression. Her performance in the ring meant nothing after that incidence.
