I am the opposite; it detest bling. It looks cheap, to me, especially if it does not match the bridle , at least. Almost all tack with bling on it is of a lesser quality, meaning the leather and the metal fittings, and those bling things will become sources of irritation if they come into contact with the horse's skin, or yours. And, they snag on things.
Count me anti bling.
Use the saddle blanket to add color and jazz things up. You can get 2, one for each colored horse. Same tack, individual blankets.
