Hi everybody!

I need your help!! I'm taking my 6 year old niece trick or treating on Halloween and she wants me to dress up, but I don't know what to be! I was going to be CInderella again, but my costume got shredded in the washing machine Help!!

My only rules are 1)cheap (I'm a poor college student lol) 2)simple and 3) warm (we live in New England and it's usually in the low fifties to mid/low forties on Halloween night)

thanks in advance!!
