Rosie is an eleven-year-old girl who loves to wear her pyjamas! Her hair is brown and is in two pigtails. She always wears her red long-sleeved pyjama top with a pink heart in the center, her scarlet long-sleeved pyjama bottoms with black dots on them, her fluffy crimson sleeping gloves, her light red slippers with yellow stars on them, her ruby red nightcap and her red frilly sleeping mask. She lives in a two-story house with her six friends. Together, they're known as the 'Rainbow PJ Girls' because they wear their pyjamas in a certain colour. Rosie is the leader of the Rainbow PJ Girls. She is a very mature, friendly, kind and loving girl.
