Mandy White is the protagonist of the book Bad Girls by Jacqueline Wilson. She is shy, sweet, timid and gets bullied by Kim, Melanie and Sarah. But she befriends Tanya, who lives opposite to Mandy. She also becomes friends with Arthur King.
Mandy has long blonde hair tied in two plaits, blue eyes and glasses. She usually wears a green bunny cardigan, yellow t-shirt and blue skirt.
Mandy is shy and timid, but is a sweet girl. She perhaps does act a bit younger that she really is, but this is due to her parents, especially her mother, treating her as if she's six rather than ten. Mandy realises she looks babyish for her age, and frequently wishes she could be more like the other girls her age.
