I have been invited to a masquerade party. Immediate yay from me because I love costume parties . However I then find out the kids are invited too and now I am slightly panicked. What sort of kids costumes will be ok? They have heaps of superhero, star wars, etc costumes, would they be appropriate?

Also, too cliche to have girltwin in a mini version of my outfit? I'm going as a ladybird.
