You know the classic sexy lingere Christmas Present type outfit? Basically, a girl with ribbon wrapped around her strategically, and a bow?
Take that idea and make it rated G.
Have a pony with ribon wrapped around it like a package. Either real ribbon, or painted on ribbon.. Have the ribbon end at the tail, and do a tail of curled ribbons in the color of the ribbons around the pony, or make a
bow for the tail out of tightly curled ribbons. You could just do the hair in tight shirley temple ringlets so they look like curled ribbon too.
Party Pony!
