I found a "Princess in a Tower" party invitation on Home Publishing and wrote the invitations out to say "Princess Jessica of ............ (surname) invites Princes Amy of Smith (guests first and second name) to attend her 6th birthday party to be held in the Ballroom at (your address). I made sure to state that it was fancy dress and mentioned that I planned to put a little make up on the girls so that there were no upset mothers. To pretty the invitations up, I printed them on different colored paper and decorated them with lots of glitter and stars.
