Themed party

Hannah will be 16 on Sunday, and tonight she is having a 'gathering' (her word) for 16 friends from school. It's a fancy dress affair, with guests required to come as something beginning with either H or C (Hannah's initials), Hannah is dressed as Cat in the Hat, thereby incorporating both initials! However, as I am banned from going downstairs, I'm unable to report on what other outfits are on show!
