We have seen the pin on the jacket before. It is the black and pearl pin. Where there is a cluster of pearls in the center and black petals with pearls on the end. She has worn it several times. I believe she has a new pearl ring she wore.
The dress and jacket are new for Mary.
As for Christian, as I said in the Denmark session. He was dressed right. He had a suit jacket on. Which he took off later. He needs loose clothes as he is a toddler and a boy. They don't sit still. And as a mom of a baby boy, there are only 2 things you can dress them in. A suit jacket, like Christian wore, which is expensive. Or a sweater vest. There isn't much dress up for boys.
