Maxima usually shuts it down for Big events like weddings etc. It seems to me that the day or more casual evening looks have really lost something in the last year.
I think that she dressed more thoughtfully during the first few years of her marriage. A bright, fresh elegance. Lately it seems that she has thrown caution (and her stylist?) to the winds and dresses (particularly in the daytime) to please herself and to hell with what anyone else thinks! Perhaps it reflects a kind of security in her role as wife and crown princess.. Which is good. But it certainly has been more "miss" than "hit" in the last few years. Much, much more.
