When Mannequins Come to Life!

What's wrong with this picture? The girl on the left appears to be a living, breathing girl - the other I'm not so sure about. Miss Cable Knit is seriously creeping me out. She has an unearthly pallor, dead eyes, stiff posture and a hideous wig. But why would a YA novel be about a mannequin? Unless it's the story of a lonely, friendless girl who gets in touch with some dude named Lars and with his help gets a BFF of her own! But she specifically asked for the long haired model, dammit!
