Not so mellow yellow! Queen Maxima steps out in an eye-popping acid dress on her 45th birthday for a royal visit to The Hague 

She's never one to shy away from a bold outfit choice, and today Queen Maxima of the Netherlands made sure all eyes were on her as she stepped out in a bright yellow dress on her 45th birthday.

The Dutch royal wasn't celebrating at a glitzy party, however; she was visiting the World Forum in The Hague for the first anniversary congress of the Federation of the Dutch Pension Funds.

On what was a rare appearance out without her husband King Willem-Alexander, Maxima seemed keen to make an impression.

No birthday cake here: The Dutch royal on an official visit to the World Forum in The Hague to mark the first anniversary of the Federation of the Dutch Pension Funds

She wore an eye-popping yellow midi dress with an intricate floral design and flared sleeves, believed to be from her favourite Dutch designer Natan.

She paired her frock with a matching yellow clutch and pointed suede courts, with her blonde highlighted locks swept worn loose and swept into a side parting.

The mother-of-three completed her outfit with a pair of silver drop earrings and a collection of bracelets. 

She wore the same dress last year when meeting President Benigno S. Aquino of the Philippines in Manila. 

The World Forum, located in the Dutch coastal city, was today officially celebrating the first anniversary congress of the Federation of the Dutch Pension Funds (Pensioenfederatie). The organisation claims on its website to look after the pension interests of some 5.6 million participants in the country.

Maxima, who is mother to Princesses Catharina-Amalia, Alexia and Ariane, was born in Argentina and married into the Dutch royal family in 2002, after meeting her husband-to-be in Seville in 1999.

Despite apparently having no idea he was heir to the throne when the pair first met, she later became Queen consort when her husband was crowned in April 2013.

Last month the close-knit family made a group public appearance when they came out en masse to celebrate the national holiday King's Day in the city of Zwolle. 

Maxima put on a typically colourful display in a fuscia pink top and cardigan worn over a floral A-line skirt from Natan.

Busy lady: Last month the close-knit family made a group public appearance when they came out en masse to celebrate the national holiday King's Day in the city of Zwolle, and she also recently visited Bavaria and France

It has been a busy few weeks for the Dutch royals, with the 48-year-old monarch and his wife recently returning from working holidays in Bavaria and France.

During their tour they had the chance to visit an art gallery in Munich, as well as trip to BMW's exhibition centre to discuss ways to increase sustainable urban mobility.

Maxima appeared to have opted for a more pared back fashion choice after donning a grey coat earlier this month with a beaded pattern that onlookers suggested strongly resembled the swastika.

The couple were visiting Nuremburg's Medical Valley Center on Thursday and the royal looked smart in her grey coat with flared sleeves by Danish designer Claes Iversen.
