What is a good costume for a horse Costume Contest

I am thinking about setting up a Costume Contest(mounted/unmounted) at my barn and would like some ideas for costumes that don't involve putting fabric or cardboard on my horse

I would enter my GIANT black Perchy gelding, my little bay arab mare, or my big warmblood chestnut mare

The arab is fine with anything, but she would be unmounted, as she has a rotated coffin bone and cannot currently be ridden.

The Perchy boy is a big baby, but would also be unmounted or at least bareback with a halter, because he's massive. I may have another girl from my barn do him with me, because she is the only one who's comfortable enough with him.

The warmblood is gorgeous, but is super sensitive skinned.

I would be willing to use massive amounts of twinkle glitter and hoof polish, except on their faces(and on the warmblood)

I have

Flame polo wraps, leopard wraps, red wraps, and I can borrow zebra or green(checkered or solid) from some girls I know.

for the arab I also have leopard and glitter bell boot

If I were you, I'd outfit the arab mare in all leopard-print (saddle-pad, bell boot, and polo wraps) Also paint her with black leopard marks. They're easy to make if you dip your fingers in the black nontoxic paint/dye and hold all four fingers in an arch together with your thumb slightly seperated finishing the circle.

Once you have her all outfitted, dress yourself like a cave/jungle woman and I think it would be a neat effect.
