Male equivalent of a Fairy?

[Mother Goose]

I'm throwing DD a party for her 3rd Birthday. There are 2 boys coming. I want to write on the inviite to feel free to come dressed as a Fairy... but what is the Male equivalent of a fairy?

And also, I am happy for people to bring parents but because we're short on space - I want to limit to 1 parent per child and am not fussed if they don't come at all... is the following ok to put on it?

You're not obliged to bring a parent,
But if you'd rather one be present;
Please please keep in mind,
That here space is hard to find;
Just one parent will be fine,
Otherwise you can borrow mine!
