THEY CALL THIS SLIM?

I keep reading news articles on the Internet about Kim Kardashian looking slim again after giving birth to her baby girl.  The above was one of the latest photos which were published very recently.
Maybe it is just me but try as I might but I don't think that she can be described as slim.  Actually she is anything but slim.  Voluptuous, a big YES.
From what I understand of the word slim, the person who could be described as such after giving birth is the Duchess of Cambridge, Katherine Middleton (pictured below).
