The third and last dress is of Queen Beatrix who was inaugurated at April 30, 1980. She wore a silk dress which was painted in the colour of the ermine of the coat she had to wear. The dress had special sleeves, inspired by a painting of the English Queen Anna Boleyn. As Beatrix had to raise her arm to swear, she wanted the sleeve to be kept in place and not sliding along her arm.
In fact she had two sleeves, the inner was with folds quilted together and kept perfect in place as you can see here. The dress was made by her personal designer Theresia Vreugdenhil, who made all her official clothes.
And here an offical portrait of Queen Beatrix with the ermine coat.
