Compliment or insult??

guys and girls, if you were to say to a girl that they look like a barbie doll, or any other kind of doll, particularly their hair, would you mean it as a compliment or insult?

thanks for the responses everyone... but... what if they only said you looked like a doll after your change in haircut and color? But mind you, my hair is not blonde, it's an auburn color and long with a blunt fringe... most prob insult right?
