Yes, and they appear to have deliberately coordinated colors, which is very nice!
BTW...there was a poster on this thread who pointed out the similarities between Dimitri/Charlotte and Caroline/Robertino(Rossellini) from many years ago...the son of an iconic actress with the daughter of a glamorous princess who happened to be friends. I think the poster deleted his/her comments before I could answer. I agree with him/her.
Robertino Rossellini and Princess Caroline had also recently lost their respective mothers, which gave added poignancy to their relationship.
The difference with Dimitri/Charlotte-as far as I can tell-is that they seem much more connected and passionate about one another than Robertino and Caroline did in the early 80's when they were together. From what I can remember of seeing photos of the two of them they had more a friends vibe than a romantic one. There was no chemistry at all, and I was not really surprised that it didn't last. Caroline in particular perhaps needed someone like Roberto- a devoted childhood friend-in the wake of her painful divorce from Philippe Junot.
BTW...I have no idea if Dimitri and Charlotte ever encountered one another as children.
