On Saturday afternoon (8 June), Prince Louis of Cambridge stole the hearts of the nation with his very first Buckingham Palace wave at the 2019 Trooping the Colour parade.
But it wasn't merely his adorable enthusiasm which left royal fans cooing, as the one-year-old also paid sartorial tribute to Prince Harry.
For the Queen's 93rd birthday celebrations, the tot was dressed in his uncle's regal hand-me-downs.
In the images, Prince Louis can be seen wearing a white shirt with blue embroidery and matching shorts that Prince Harry first wore to the event at a similar age back in 1986.
It's also interesting to note that the Duchess of Cambridge colour co-ordinates with Princess Anne in the photographs, as she chose a sunny yellow Alexander McQueen coat dress for the prestigious ceremony this year.
Although it's not the first time the Windsor clan have passed clothes down through the generations.
For Prince George's Trooping the Colour debut in 2015, the one-year-old wore his father's baby blue ensemble complete with a white ruffled collar.
Most recently, Prince Louis has also been borrowing from his older brother's wardrobe.
The Duke and Duchess of Cambridge's youngest child was photographed at the RHS Chelsea Flower Show in a pair of familiar red striped dungarees last month - first worn by a nine-month-old Prince George during the royal tour of Australia in 2014.
Demonstrating the 'George Effect', the £40 Neck and Neck one-piece sold out within 24 hours.
