Kate Middleton’s dress when she emerged with her newly-born son from St Mary’s Hospital – blue with white polka dots – brought back memories of when Princess Diana had left hospital with her firstborn son, William – now Kate’s husband – wearing the same type of dress, with the only difference being the colour, which was green,.

The Duchess of Cambridge seemed to be paying a small tribute to the late Princess Diana in her wardrobe choice, international media are reporting.

Holding the Prince of Cambridge in her arms, Kate walked out of the Lindo Wing of the London hospital wearing a simple pale, baby blue dress covered in white polka dots.

Thoughts immediately jumped back to that day 31 years ago in June 1982, when it was Prince Charles and Diana who came out of the same hospital wing, holding baby William.

On that day, Diana wore a dress also covered in white polka dots.

Like his father did before him, William took his son from Kate and held him while addressing the crowd.

However, unlike Charles and Diana, who only lingered briefly before getting straight into a car and leaving the hospital, William and Kate took a few minutes to approach the crowd and answer a few questions.
