The cute detail you probably missed about Prince Louis’ birthday pic

Yesterday, the Duke and Duchess of Cambridge marked Prince Louis' first birthday with a series of adorable portraits. ahead of his actual birthday on 23rd April.

Like with Princess Charlotte and Prince George's official portraits before, these were taken by mum Kate Middleton, in the grounds of their home in Norfolk.

Louis is seen smiling and generally having a bawl, and in two of the shots he wears a cute burgundy knitted jumper.

In the third shot though, he poses in a super cute puppy jumper, which some believe is actually a nod to his grandmother's love of her Corgis. Others pointed out that it was similar to the solider jumper Prince George wore in his first birthday portrait, in that it had a cute motif which was so quintessentially British.

Either way you look at it, it looks adorable on him. It's by British brand Trotters and cost just £35, though of course within just a few hours of the photos being released, the jumper sold out.

Here's hoping it gets re-stocked soon.
