Well, in some ways, it could hurt a childs image of what their body should look like. If u really look at Barbie or Ken, they have so called ''perfect'' bodies. Honestly, if a woman were to have Barbies exact body & measurements, she would have to be 6'9'' tall. Really, how many women do u see that r that tall?
I really think girls, no matter what age they are, should be happy with who they are. When a girl sees Barbie & all the clothing that goes with it, they may think that, that is how they r supposed to dress & look like.
But it can go the other way too that Barbie is just a doll & by a girl playing with her she is using her imagination by her making up what Barbie is doing, wearing & so on.
