Several photographs of Prince Louis were released over the weekend to celebrate his fourth birthday. Kate Middleton and Prince William’s youngest child was pictured wearing a grey jumper with stars across the chest. It has now been revealed, that the jumper previously belonged to Prince George. 

The youngest Cambridge child had been dressed in a grey cashmere jumper. 

It is from the brand Olivier London, and its 2017 collection, thus making it older than Louis who was born in 2018.  

The brand said on social media: “Happy Birthday Louis. Thrilled to see our Star Jumper still going strong, a lovely testament to the long lasting nature of our cashmere. Have a lovely day Louis.”

The jumper is decorated with four colourful stars, which range from red, to blue, to yellow and then navy.
