I absolutely love her dress. It is gorgeous on her. Have any photos of Caroline at any of the birthday events been released? I haven't seen any, but I would imagine that she attended.
Edit: Never mind. I just found one of Caroline:

It looks like this was at the gala. She looked really beautiful, and she is wearing her LIW ribbon, so I guess that she was there in her capacity as LIW, not just as a guest.
