Well... Are you going to show a HALLOWEEN COSTUME party so like Anne hathaway?You should go as fan girl
-black sequined dress, head wrap with feather attached to it
- Marie Antoinette and you can wear a really lacy fancy dress with a curly wig with little accesories in it like roses or little fake birds that you can get from a crafts store(that's like what they put in there hair in those days)
-A peasant girl and you can wear a dress with a corset bodice and you could wear an apron
-a fairy would be cute because you can wear a bright dress that can be short, but not too short and it can have little puff sleeves and you can wear your hair curly with flowers entwined in it, and lastly get really pretty wings.
