Kate looks lovely, I like the colour and I like the kicky feathers on the hat. The shape is nice too. I always make a bit of a wincey face whenever an outfit shows off how thin she is, but that's my own thing.
I saw the little video clip of them walking in and Kate looked like she had literally saved up some word vomit to fling at Harry as they approached the entrance. It was kinda funny and actually completely unnatural - they had done the entire journey together but now suddenly there was this super animated conversation they just had to have as they were passing the press?? Lol.
That said, however premeditated, it will certainly work! She's really gotten so good at this.
