Lulu is a little girl who always wears a pink footsie pyjama onesie with sparkles and unicorns on it, a pair of lilac sleeping gloves, a pair of magenta slippers, a lavender nightcap with tiny red hearts on it and a magenta, frilly eye-mask. She lives at a large house, which is also a pyjama-loving all-girls boarding school with her 10 classmates.
