Royal Outfit of the Day: June 30

Alexandra, Countess of Frederiksborg (formerly Princess Alexandra of Denmark, first wife of Prince Joachim) turns 50 today! (Or so her 1964 birth date would have us believe; the lady herself hasn't aged in, well, ages.)
Not passing up any occasion to feature the Alexandrine Drop Tiara, today's outfit is a late model Princess Alexandra gem, if you will. Worn in the later years of her marriage as well as during the period after her divorce when she was still attending state occasions, the design is a bit more sleek than some of the enormous gowns she sported at the beginning of her marriage. But in keeping with the example set by her former mother-in-law Queen Margrethe, it still features a nice train. (The train is best seen on video, below.) The blue silk gown with swirling embroidery and floral embellishment is from Henrik Hviid, a favorite designer.
Video: State banquet for the President of Bulgaria, 2006. Alexandra enters at 1:55, and there are plenty of other royal sighting in there too - including one of my favorite Mary gowns. Part 2 is here.
She's long since ditched the big princess gowns, but she hits 50 elegant as ever. Happy birthday to her!
