She's barely a month old and Princess Charlotte is already following in her mother's footsteps.
The Duke and Duchess of Cambridge releases four precious photos of their eldest son Prince George with his newborn sister on Saturday night and the photos set the baby fashion industry alight.
The little princess wore a woollen jumper and bodysuit from designer Polarn O. Pyret, retailing for €20, which has nearly sold out online.
George's outfit, the same blue and white shorts and shirt combination he wore to first meet his sister, was designed by Rachel Riley and his knee high socks were chosen from Kate's favourite children's story Amaia Kids in Chelsea.
It's little surprise that the royal babies selling power is apparent at such a young age with the 'Kate Middleton effect' boosting sales of every item their mother wears. And little George's outfit for her Christmas portrait sold at a similarly fast pace as his sister's first official photo.
The Duchess of Cambridge has broken royal tradition by taking the photographs herself as high profile photographers such as Lord Litchfield, Cecil Beaton and Lord Snowdon have often been enlisted to snap the new royal arrivals.
Kate is a keen amateur photographer and studied history of art at St. Andrew's in Scotland, where she met Prince William.
Kensington Palace tonight shared the photos of the royal babies on their Twitter and Instagram accounts to "recognise the hundreds of thousands of additional people who have followed the official Kensington Palace accounts in the month following the birth of Princess Charlotte".
Earlier this week it was announced that Princess Charlotte will be christened at St. Mary Magdalene Church on the Queen's Sandringham Estate on July 5. The private ceremony led by the Archbishop of Canterbury, Justin Welby.
The venue is a tribute to Prince William's mother Diana who was christened there in 1960.
