A fantastically funny, perfectly pink picture book about a little girl called Polly and her beloved pink pyjamas.

Polly loves her pink pyjamas she wears them all day long! But she can't wear them to Fred's party, so her friends Poppy, Clara, Henry and Sally all lend her something of theirs. Finally Polly is ready to go but she looks so funny in her borrowed outfit that she can't go after all! Things are looking bad until her friends reveal that the party is, after all, a pyjama party!
