Future Queen of Spain Princess Leonor, 18, dresses warmly in a chic coat to join her mother Letizia and King Felipe at the opening of Parliament in Madrid

Queen Letizia of Spain is known for her fashion prowess – and if Princess Leonor’s latest appearance is to be believed, it looks like the apple didn’t fall far from the tree.

The 18-year-old heir to the throne joined her parents, including father King Felipe, 55, at the solemn opening of the 15th parliamentary term in the Spanish parliament in Madrid.

For the occasion, Leonor stylishly presented herself in an emerald green dress with a flowing skirt and elegant sleeves, which she combined with a light brown coat and matching heels.

She wore medals around her neck, while she added a touch of glitter to her ensemble with a pair of dainty gold earrings.

Leonor completed her look with a matching coffee-colored clutch bag and added a touch of glamorous makeup to her features.

Her mother, Queen Letizia, 51, looked equally fashionable in a red A-line dress with long sleeves and matching heels, paired with a black cape.

She wore her chocolate brown locks down and swept them behind her ears, revealing a pair of diamond earrings.

The queen wore a glamorous makeup look for the event, with a coral shimmer smokey eye and matching lip color.

King Felipe, meanwhile, looked dapper in a blue tie, white shirt and jacket as he attended the occasion with his family.

His youngest daughter Infanta Sofía probably did not attend the event because she is currently studying at UWC Atlantic College in the Welsh province of Vale of Glamorgan.

The school is often referred to as ‘Hippie Hogwarts’ due to its progressive approach to education and picturesque castle setting.

In October, Princess Leonor received a monumental welcome from royal fans on her 18th birthday.

The Spanish capital was bustling with huge crowds who gathered outside the Congress of Deputies in Madrid to show their support for Leonor after she took an oath of allegiance to the Spanish constitution.

Royal fans swarmed around the car where the maid of honor sat with her younger sister, Infanta Sofia, 16. The princess delighted fans as she smiled at the crowd as they gathered around the car to catch a glimpse of the heir.

A sea of ​​Spanish flags of all shapes and sizes accompanied the warm reception by royal fans.

On her 18th birthday, the teenager pledged allegiance to the Spanish constitution, meaning she can now officially act as regent in the absence of her father, King Felipe.

As she swore allegiance to the Spanish Constitution in parliament as her family and government representatives looked on, Leonor’s experience in public speaking was clearly visible, with a proud and steadfast presentation.

In a speech delivered to the nation after the ceremony, the princess reaffirmed her commitment to the Spanish people, and in turn asked the Spanish to have faith in her as she stepped up her role and became a queen in training.

And a moving yet poignant moment came when the king presented his daughter with the Collar of the Order of Carlos III, the highest civilian honor in Spain.
