The big mistake Prince George and Princess Charlotte's wedding outfit designer made.

Prince George and Princess Charlotte looked absolutely adorable at a wedding this past weekend, but the label behind their outfits has found itself in a pretty awkward situation.

The cutest royals were part of the bridal party at the wedding of Sophie Carter, one of the Duchess of Cambridge‘s close friends, and dressed by London-based childrenswear label Amaia Kids (you can see the pictures here).

Shortly after the wedding, the brand, which is a favourite of Kate’s, shared an image of the custom flower girl and page boy outfits to Instagram.

It didn’t specifically reference the wedding, but eagle-eyed royal fans quickly spotted the George and Charlotte’s names written on labels above the outfits which confirmed the link.

Amaia Kids removed the photo, with a spokesperson saying: “The picture was removed as it was not for publicity purposes in case it was wrongly used.”

Photos published by PEOPLE show George, five, wore a white shirt with sky-blue pants, white stockings and white loafers.

Three-year-old Charlotte is the goddaughter of the bride. Her flower girl outfit was a white dress with blue piping.

Their mum Kate recycled an outfit she'd previously worn during a tour of Germany last year. It was a rare public appearance for the Duchess, who is still on maternity leave following the birth of Prince Louis.

While George and Charlotte were a super cute addition to the wedding, five-month-old Prince Louis stayed at home.
