Stop tell how about skinny is that girl. It's horrible! It's like tell someone how fat she is. Is very sad to see how the world cares just with the 'fat one', and not with the 'fat one and the skinny one'.
It gives a good message out though. You see people with fake breasts, are you complaining about that? If not, complain about them. Because no matter how fake it is, it gives others thoughts. :)
