Isla is a sweet ten-year-old girl with brown hair and blue eyes who loves to wear her pyjamas. She always wears a bright pink long-sleeved pyjama shirt and bottoms with yellow stars on it, a pair of magenta sleeping gloves, a pair of light pink socks, a pair of lavender slippers with hearts on them, a fuchsia nightcap and a purple frilly sleeping mask. She lives in a lovely house with her three sisters Izzy (eight years old), Ida (six years old) and Ivy (four years old).
