Prince Albert and Princess Charlene of Monaco: Princess Charlene topped her pale suit (love the pearl floral buttons!) with a sleek beret percher hat simply trimmed with a knotted bow at the side. The hat looks to be covered in the same barely-blush hue as the suit.

King Willem Alexander and Queen Máxima of the Netherlands: Queen Máxima wore a structural white straw saucer hat with brim extension and flying bow. The vertical design of the hat pairs so beautifully with the exquisite applique lace cutout on the bodice of her dress.

King Felipe and Queen Letizia of Spain: Queen Letizia wore the largest hat we’ve seen her in to date, a design in natural hued straw with mushroom brim and button crown, draped in an overlay of widely woven (I think it’s vintage?) bubblegum pink net veil. It’s a dramatic design for Letizia and so wonderful to see her experimenting with new millinery shapes.
