So am I the only parent of high school pupils that thinks this is a bit ridiculous.
My dd has a letter saying dress up for world book day or detention... and characters that wear normal clothes are not allowed.
Now I personally hate dressing up and if invited to a do I'd not go rather than dress up and feel a twat.
Honestly at school I'd have bunked off. No way would you have got me in there dressed up!
Also I now have to go and spend however much on a dressing up outfit for a 14 year old who will never wear it again!
