you could braid/plat his mane and tail a few days before hand so it goes all wavey and curly, put glitter all over him, tie ribbons that are the same length as his mane right at the top so there is colour flowing down with his mane and tail, ummm....... you could get some of those stick on diamotes (sorry bout spelling) fake crystal things to stick on his face...... and paint his hooves with that black tar so his hooves are black and have a pretty sparlkly bridal. Just make him look magical. I think that would look awsome!!!! And you could dress up all pretty and where long flowing cloths that would like drape over him and down his side!
