It's very nice to see that. It seems as though the birth of Prince Hisahito has taken a lot of pressure off the Princess. Although I do wonder if she's growing her hair so as to be different from Princess Kiko.
i was wondering of that too. but masako sure looks good in long hair, makes her look more youthful. compared to mary who puts too much make up, like a kabuki actress as one poster here puts it, masako has very light make-up and still manages to look young. must be the light make-up or her asian genes though.
as for kiko, she seems to be the only japanese royal who doesn't have a problem of the grey men in the court. she seems very eager to step into masako's shoes.
