If you have time, try and order those ears early or call the Disney # ( sorry I'm not sure which it is , But I am sure someone on here know) order the pink ears and get some pink rhinestones from Hobby Lobby or a place for crafting and then take some E6000 and glue on a big 16 in rhinestones on the ears. You could add some spray glitter. That would spruce it up a bit. or take supplies when you go down there and decorate there. Hope that gives you another idea.
Any ? on hope to apply them just PM me I'm glad to help.
