In case you missed it, Kensington Palace released adorable new photos of Prince Louis, the youngest child of Prince William and Kate Middleton, ahead of his first birthday.

Captured by the Duchess of Cambridge herself, the photos were taken at their family home in Norfolk and showcase the young Royal’s new pearly teeth (all TWO of them) and combed-over hair.

Plus his adorably enthusiastic smile.

But there is one tiny detail that we all missed, picked up by eager Royal fans, who tend to have an eye for these kind of things.

In two of the photos, released by the official Kensington Palace Instagram page, Prince Louis is wearing a maroon jumper paired with navy shorts and knee-high socks. Look familiar?

These navy shorts – reportedly by the brand Amaia Kids Clothing – were also worn by his older brother, Prince George, for official Christmas photos in 2014. The photos of the eldest child of the Duke and Duchess of Cambridge were taken when he was about 17 months old.

In the photos, Prince George who is now five years old, wears the same shorts and an equally adorable smile, although a little less enthusiastic.

Yep, even the royals do hand-me-downs, albeit they usually come in the form of much more luxurious items such as the Queen's tiaras. But STILL.

Kate Middleton is known for recycling her own outfits to many official events, and she also recycles her own kids' clothes just as frequently.

The shorts worn by Prince Louis here, first worn by Prince George, were also worn by the youngest Royal for their family photo, also released by the Kensington Palace Instagram page, in December last year.

We're guessing we might see these hand-me-downs be passed on to the next Royal to be born: Prince Harry and Meghan Markle's soon-to-be-born child, with the Duchess of Sussex now at the pointy end of her pregnancy.
