How would you do a Queen of Hearts costume for a horse?

are you the one who is going to be the queen? i feel like that would work best. i would dress yourself up as the queen and then dress your horse up like how the jousting people do and have the fabric off the sides as cards i think that would look awesome and then decorate the rest how you would like. hope this kind of helps. like this kinda but with cards....http://www.bbc.co.uk/es/content/images/2007/07/02/07_castle_horse_470_470x352.jpg
