The Duchess of Cambridge donned a polka dot dress for her first appearance after giving birth – as did her late mother-in-law 31 years ago.

The new mother sported a blue Jenny Packham frock as she and William introduced the newborn prince to the crowds outside the Lindo Wing of St Mary's Hospital on Tuesday.

Princess Diana wore a green polka dot dress as she exited the same hospital following the birth of William – with many commentators interpreting Kate’s choice as a nod to her husband’s mother.

Indeed the Duchess is a fan of Packham, choosing to wear an elegant nude dress and matching coat by the designer for her last public appearance before the birth.

As with so many of her fashion choices, demand for Kate’s post-baby dress caused the website for the British designer to crash.

But a spokesman for Packham told the Daily Mail the dress was a one-off and is not available to buy.

When asked if the designer had created a pink one in case the royal baby had turned out to be a girl, she replied: “I couldn’t possibly comment.”
