I had an elf hat on with ears sticking out the top. That's as close to a costume as I'm going to get.
Good luck on the snow. I think it's too warm to have any stick. Sounds like a mountain pass trip may be necessary to give your daughter a WHITE XMAS! Enjoy her while she's this age. Take lots of pictures. You'll enjoy them now but more when she's grown and gone. Bobwins
