Dear G.,
Don't worry about your daughter because my now 17 year old daughter always wanted to be some scary, gross looking monstser on Halloween. I tried my best to talk her into a princess costume or just something cute, I even made her be Belle from Beauty and the Beast one year. When I saw how unhappy she was that year I vowed to let her be what she wanted from then on. She will grow out of it and it definitely doesn't affect who they become later because my daughter is the average teenage girl now (all about clothes and boys). Part City has every costume you could imagine and the sizes run from infants to adults so I'm sure you can find what you're looking for and they have great accessories also. There is one right by Burlington Coat Factory in Lansing if that's close to you. Good Luck!
