Thank you very much for ceating this thread!!! As much as I like the topic, it really bored me to read about it in each thread.
IMO the three look much alike. Of course charlotte and caroline more than each of them with Grace, but they got her - I think you call it jaw - and facial bone structure - Charlotte more than Caroline.
I can't say, who's the most beautiful. I used to think it was Charlotte followed by Grace, but now I can't say so anymore.
I love the cool blonde from movies like to catch a tief, IMO she was the most beautiful women of her time. I think the same about Charlotte.
For me it is not so easy to compare them because I don't know any paparazzi pictures of Grace during her teens or twentie, probably because there are none. So comparing a Red carpet or movie picture to a picture of someone shopping in a supermarket somehow doesn't work - specially as I prefer the latter one. I mean the special thing about Charlotte is, that she looks great without makeup in jogging clothes, eating someting. I don't know what Grace would look like in this situation.
On Caroline:
I think that she looks better today, than her mother at that age.... And: Though I prefer Charlotte's full lips, Caroline's face is less broad. Maybe it has to do with to whom you feel closest. My Mom always says that for her Caroline looks much better than Charlotte and I think I've watched that with members here, too. that they prefer the one they "grew up with".
To sum it up: They're all very beautiful in their own way
