Clothes: everyone looked fine. All the women looked appropriately dressed for church, except for MM who looked too fashion. She can't gauge these things properly, but who can blame her as an outsider - assuming, that is, that she intended to get it right.
Interactions: every family has an Edward. Props to him, stepping back and seeing the longer-term picture (life goes on and who knows what the future holds etc). Can't say anything about any of the others because I think they all know the cameras were on them and they deliberately kept things brief/curt. Except for MM: the constant smiling was weird. It was a church service, and not one to elicit high emotion. Nobody else in the photos, RF or other, smiled so keenly at any point that I saw. Can't presume to know why, best guess would be insecurity. I did notice that her attention was on William rather than on Kate, as was Edward's and Sophie's. I think there's lots of lots of old-fashioned "women know thy place", "[Catherine, for example], wife-of" in the RF. Also, everyone knows William's the future King, William's the one to defer to, he's the one on the inside, the one making decisions, the one getting the briefings, going to the meetings, the one carrying the responsibility. I think Kate is the supportive wife having babies and raising them, not an equal like H&M give the appearance of being to each other (maybe even MM pulling H along). All the more difficult for MM to get with, as an outsider.
Harry: looking at all the photos from the past few days, the man looks a wreck to me. Up and down, mostly down. He must be feeling like shit: tired, stressed, emotional, not on solid ground. I think MM was holding his hand mostly, not the other way round. He looks like a man teetering on the edge, only truly engaged with children who are guaranteed to be happy to see you and not give you a hard time. That emotion bubbling so close to the surface at the Royal Albert Hall was so reminiscent of Diana. I think he needs help from someone. Perhaps a father to take him under his wing and say "everything will be alright, son".
