Earlier on Monday, Prince William and Kate Middleton appeared on the steps of the Lindo Wing at St. Mary's Hospital to introduce their new baby boy to the world.

Wearing a red dress with a white collar, Kate Middleton looked in good health after giving birth to her prince, who is fifth in line to the throne.

When Princess Diana presented Prince Harry to the public, back in 1984, she too wore a red outfit with a white Peter Pan collar.

Her choice of outfit is being seen as a tribute to her late mother-in-law.
