to this day in 1948, 72 years ago when Dutch Queen Wilhelmina passed the throne to her daughter Juliana. The Dutch royal family (see future Queen Beatrix on the left) appeared on the balcony of the Royal Palace in Amsterdam following the abdication, Princess Wilhelmina in a feather trimmed cloche hat and the new Queen Juliana in a floral turban.
Two days later, this pair of Queens would take to the balcony again following Queen Juliana’s inauguration, Juliana in a jaunty, tall, veiled pillbox and Princess Wilhelmina in what looks below to be a flat beret-newsboy cap hybrid with satin floral trim but was actually a short brimmed hat.

Royal Hats 
I love Juliana’s oversized veiled pillbox perched on the front of her head. Very 1940s styling, but something I want to make a comeback ASAP!
Fascination vintage video of the inauguration day. Both queens step out on the balcony at 1:15.
Princess Margaret was in attendance.

Thanks, Jimbo! The procession of royals in court dress starting at about 21:00 is really something.
I like Juliana’s veiled pillbox the best of these. She looks so regal. Little Beatrix looks as though she’s having a great time.
I was so impressed with the delivery of Queen Wilhelmina’s speech! It was given with much energy! I loved the parade of hats at the end.
This video is fantastic! Princess Wilhelmina’s hat is actually a short brimmed design- it’s great to see it here because the single side view is deceiving.
