Queen Maxima of the Netherlands and King Willem-Alexander were photographed at the Central Train Station in Graz, Austria, on Wednesday.
The Dutch royal couple are on a three-day state visit to Austria.
For the morning engagement, Queen Maxima wore a floaty light blue dress.
The midi gown featured a brown floral pattern and cape sleeves.
Queen Maxima added a brown belt to the stylish summery dress.
The royal accessorised the look with a brown clutch bag and matching heeled sandals.
However, the brown headband the monarch donned was the centre of attention.
Queen Maxima chose a headband with a big brown flower on the side.
The royal is a fan of headbands and often wears them for official events, especially during the summer months.
The Antique Pearl Tiara is made of diamonds and large pearls and is a favourite of the Dutch monarch as she has been seen donning the piece on many occasions.
The brooch was the 19th-century Diamond and Pearl Devant de Corsage.
“She looks like a Greek Goddess!” said royal fan @mog1717.
“This entire look is gorgeous from the tiara to the shoes great look,” added @h_k_bend.
