I really like both dresses for both women.
Unfortunately Charlene's looks really rumpled or ill-fitting in the chest/belly area in many of the photos I saw (and she has some kind of white blobs, maybe flower petals, stuck at the neckline), but if it were more smooth, I'd love it. It's definitely more the kind of thing I could see wearing myself, whereas Kate's was totally formal, cathedral-princess, which was gorgeous, but not for me (I was one of the Pippa's dress fans).
I wasn't familiar with the issues around the Monaco wedding, as I don't usually follow these things in the news, but I can't blame her for looking less than enthused if all that's true.
