Princess Elisabeth looked like the ultimate fairytale royal as she stepped out for Belgium's National Day on Monday.
The 23-year-old wowed in a green chiffon dress by Belgian designer Natan, with the floaty number featuring a caped overlay and a tiered skirt.

She teamed the frock with gold skyscraper heels and matching accessories.
Elisabeth, who is the heir to the Belgian throne, joined her parents, King Philippe, 65, Queen Mathilde, 52, and her younger siblings, Prince Gabriel, 21, Prince Emmanuel, 19, and Princess Eleonore, 17, at the Te Deum mass at Saint Michael and Saint Gudula Cathedral in Brussels.
The princess recently returned home from completing her first year of her two-year master's degree at Harvard University in the US.
In May, President Trump's administration put a ban on international students attending classes at Harvard on a visa. The prestigious Massachusetts university pushed back with a lawsuit, meaning the rule was blocked temporarily.
While Elisabeth's future at the faculty is uncertain, royal journalist Wim Dehandschutter has said that the princess will not abuse her royal status to continue her studies at Harvard.
Elisabeth has since carried out numerous public engagements in Belgium and recently completed an internship with Bruegel, an independent research centre in Brussels, which specialises in research of (European) economic policy.

Noticeable absentees were King Philippe's parents, King Albert, 91, and Queen Paola, 87.

King Philippe also ascended the throne on 21 July 2013 so the date is extra meaningful for him.
