Several royals have traveled to Buenos Aires, Argentina to attend the 125th IOC Session which begins today. While we have not seen photos of Grand Duke Henri of Luxembourg, Prince Albert of Monaco, King Constantine of Greece, Crown Prince Frederik of Denmark, Princess Anne, the Princess Royal, Princess Hisako of Takamodomiya or Princess Nora of Liechtenstein in a hat (nor do I expect to), Princess Akiko of Mikasa was spotted with millinery at the Japanese Botanical Gardens yesterday. Princess Akiko, eldest daughter of the late Prince Tomahito of Mikasa (who was first cousin to Emporer Akihito), is accompanying the Japanese delegation to support the Tokyo bid for the 2020 Olympics. For her visit to the gardens, Akiko wore a characteristically sedate dove grey hat with rounded crown and upturned brim.
