This July 23, 2013 file photo shows Britain's Prince William, right, and Kate, Duchess of Cambridge with the Prince of Cambridge as they pose for photographers outside St. Mary's Hospital in London. Princess Diana wore a caftan-like outfit that hid the post-childbirth tummy bump when William was born. In contrast, the former Kate Middleton, in her first public appearance on July 23, 2013, after giving birth, wore a dress that did not camouflage her belly, and many women are applauding her choice.
