Three cheers for the King! Queen Máxima of the Netherlands is a vision in green as King Willem-Alexander and their daughters join her to celebrate King’s Day

Queen Máxima of the Netherlands was typically chic in an olive green dress and striking headpiece as she and her family attended King’s Day celebrations today.

The Dutch royal family was out in full force for the annual festival marking the birthday of King Willem-Alexander, this year in the northeastern city of Emmen.

The king and queen were accompanied by their three daughters: Princess Ariane, 17, Princess Amalia, 20, and 18-year-old Princess Alexia, who were all in shades of green, blue and orange.

The family walked a route through the city, collected floral gifts and greeted spectators who had gathered to wish the royal family good luck on King’s Day.

Máxima was a vision in an olive green dress with a subtle floral design.

She matched her outfit with a striking headpiece made of green butterflies and completed her King’s Day ensemble with a cream-colored cardigan, matching gloves and simple heels.

The queen also wore a pair of pearl earrings and kept her makeup simple.

Her three daughters were just as chic, with the eldest and heir to the Dutch throne also choosing to wear green. Amalia went for a blue-green shade, also with a floral pattern.

She wore a matching overcoat to protect herself from the cold weather, and she kept her blonde hair loosely curled and down around her shoulders.

Her sister Alexia wore a white dress with a deep orange overcoat, while the youngest sibling, Ariane, wore a three-piece suit in a similar rust color.

King Willem-Alexander also dressed to impress in a deep blue suit and yellow tie.

The festivities in the Netherlands celebrate the king’s birthday – who turns 57 today.

The celebrations start the night before, when people dress up in orange and take to the streets and canals.

The main party takes place in Amsterdam, while Rotterdam hosts the second largest party. Smaller gatherings take place throughout the country.

Queen Máxima attended the King’s Games in Hoofddorp yesterday – where she was a hit with the children.

The Dutch queen, 52, and her husband, King Willem-Alexander, were in good spirits as they met students from KBS Klippeholm and CBS Vesterhave.

The royals were received enthusiastically by the primary school students – and they seemed particularly excited when they saw Máxima giving them a high five in their classrooms.

The mother-of-three was also pictured sitting at the lunch tables with the students as they snacked on sandwiches, fruit and water in the school canteen.

Elsewhere, the King and Queen stepped outside to observe what appeared to be an exciting friendly game of football.

For the event, the Argentine-born royal wore a pair of high-waisted chocolate brown culottes, which served to accentuate her curvaceous figure.

Maxima paired the look with a gray high-neck sweater and brown leather boots, while for outdoors she opted for a long gray overcoat.

A pair of silver metal earrings were the perfect accessory, although she opted to forgo a handbag on this occasion.

For her hair, the royal’s luscious blonde locks were tied down and adorned only with a center parting.

Her makeup was as subtle as it was striking, with a streak of black eyeliner and a pink lip to complete the look.

Meanwhile, her husband, the King, looked dapper in a royal blue suit which he wore with a crisp white shirt and orange tie.

His outfit was a bold statement of national pride as it represented the colors of the Dutch flag, but was also synonymous with King’s Day.
