IN A sweet new picture with her father-in-law Prince Charles and youngest son Prince Louis, Kate Middleton looks gorgeous in polka dot.
The Duchess of Cambridge opted for a chic blue and white design for the snap - but she isn't the first person to wear it
Kate's dress appears to be Alessandra Rich's pleated maxi, which was retailing at £1,225 before it sold out earlier this year.
The designer piece features a full skirt, long sleeves and matching white hems and collar.
Recognise it? That's because Meghan Markle's Suits co-star Abigail Spencer wore it to the Royal Wedding back in May.
Abigail - who played Dana 'Scottie' Scott in the hit drama - paired the piece with a black belt and a navy floral fascinator.
Interestingly, Kate and Abigail aren't the only famous ladies to have donned the dress.
Ivanka Trump chose the demure maxi to speak at an event in Granite City, Illinois back in July.
Like Kate, the 37-year-old left her hair down, adding a glamorous smoky eye and pink lips.
She accessorised with a loosely-tied white belt, creating a more casual vibe than Abigail's high-end wedding look.
Who wore it best? To be honest, we reckon little Louis stole the attention from them all.
In more royal news, this is the touching reason Sarah Ferguson wore green at Princess Eugenie's wedding.
Prince Harry and Meghan Markle have lost THREE of their private staff in six months and experts say it's 'looking like a stampede'.
And Pippa Middleton has 'named her baby son' with a touching nod to her dad and brother-in-law.
