Regarding Queen Rania and Asma Assad, remember these are rich women who can afford the best hairdressers, makeup artists, and designer wardrobes. Asma Assad doesn't look especially thin that picture either. And while Queen Rania is thin, who knows what she really looks like without her makeup and her hair done.
When I was in college a friend of mine had this book called Scavullo On Women. The book consisted of photos of famous women taken by the late photographer Francesco Scavullo (who photographed many magazine covers for Cosmopolitan). Anyway, this book had before and after photos of each of the women. The before photos were taken in black and white. The women had no makeup on, and their hair was not done up at all. The after photos showed them with their hair and makeup in full color. And no doubt for the after photos, Scavullo must have also used appropriate lighting.
Needless to say, the pictures were like night and day.
