It's a form of individuality, she rocks the feathers and looks awesome and kicks ass with the feathers. She'd kick ass in the ring with or without the feathers. Get over it!
I am not a big fan of her hairstyle, I mean horse riding has codes and traditions we are proud of (the white breeches, show jackets...). The show ring is not really the place to wear that kind of hairstyle, it's like wearing a fancy equipment, I don't really like it. I prefer to focus on what really matters: the horse and horse riding.
Just like Molly I find it really cool! I don't know if there is a risk in case of a fall but I don't really think so
Personally I love it, it's cool to see things different in the ring. We are so used to see the same outfits, the same helmets, the same haircuts...
It's fun and it doesn't change at all what a great rider she is 🙂
