Numerous world leaders were in Japan this week for the G20 Summit- on Thursday, the emperor and empress welcomed French President and Mrs. Macron to the Imperial Palace for a luncheon in their honour. While the empress, as hostess, did not wear a hat, the Imperial princesses in attendance did.

Princess Mako and Princess Kako both wore silk covered bumper hats trimmed with bows at the back. It’s difficult to tell- I think Mako’s hat and suit is an almond beige while Kako’s looks to be a blush pink.

Princess Nobuko of Mikasa wore a grey hat with Pork pie crown and rolled brim trimmed with a darker grey hatband and bow at the back. Princess Hisako of Takamado topped her blue and grey floral print suit with a repeated ivory saucer. The hat features an ivory windowpane crin inverted binding around the brim and is trimmed with pale blue silk ruffled flowers on the side.

The most interesting hats of the day were on Princess Yoko of Mikasa, who wore a white hat with wide, curved brim and tall pinched crown, trimmed with a pale turquoise hatband and Princess Tsuguko of Takamado, whose hat featured a navy crown with ivory wrap and ivory brim with a stripe of navy binding. With her navy and cream ensemble, the hat topped a crisp and very summery look.
