Princess Kate wore a new £3,000 Erdem suit to the Commonwealth service

On Monday, the Windsors celebrated Commonwealth Day by going to church for a Commonwealth service. This was famously the same event which served as the Duke and Duchess of Sussex’s final appearance as working royals, the finale of their You Coulda Had a Bad Bitch Tour. Three years later and… a lot has changed. Everyone seems smaller and yet… more chaotic? The drama is still there, even minus the Sussexes, although the glamour definitely left with them.

The Princess of Wales loves to cosplay other people – QEII, her mother, Crown Princess Mary and, of course, the Duchess of Sussex. But we often forget that Kate also loves to dress up like she’s in Downton Abbey, which used to be one of her favorite shows. That’s the vibe Kate gave me in these photos – Edwardian cosplay, Lady Mary vibes. Kate wore a new £3,000 Erdem suit and a diamond Prince of Wales three-feather brooch (which looks a lot like a fleur-de-lis). Apparently, King Charles gave it to Kate as a gift. Interesting. Charles used to “give” his PoW-branded stuff to his mistresses. I doubt that’s the case here. Anyway, I really dislike Kate’s ensemble. All of that money for something that looks like a cheap Downton costume.

Queen Camilla’s outfit is by Fiona Clare, and she wore an unsecured Philip Treacy hat which she had to hold onto in the wind. The new Duke and Duchess of Edinburgh were there too – if anything, Sophie’s the one doing Meghan cosplay. What is with Sophie’s wreath brooch?
