NO matter how much silver or how fancy your outfit is, if the horse does not perform, you are not going to win. Now, if all things equal in performance with two horses, the appointments could make a different. After all, you are showing and want to look nice. Some of the outfits are gaudy, but heck we used to wear fringe. :0
I only showed a little western, but I think when we did it we held the outer seam of our jeans. And yes, there was lots of fringe, and super long chaps that made everyone look long legged and heels down.
