A rare miss for the Queen. Normally she is impeccably dressed, but this does nothing for her model-like figure and hair. I do wish she would change up her style just a bit and maybe get away from always wearing couture in the evening. Of course, even in these economic times, she can afford it. Please don't take this as bashing her, because I'm not and I think the work that she does is very impressive, but I wonder if you put her side by side with a model from Paris, a semi-educated "Joe the Plumber" wouldn't be able to tell you who she is. I think she needs to add something to her style that says "I'm a Queen" and I don't think it necessarily needs to be the latest trend from Paris, New York or Milan.
QEII is obviously always recognizable, but QR isn't. Of course, she is a modern Queen Consort and doesn't really have any contemporaries her age that we would compare her to.
As I said, rare miss, but the color looks great on her. Didn't Princess Marie of Denmark wear something very similar to this but only in purple/eggplant? I think she wore it to a dance to celebrate the Guard's anniversary.
