FILE - In this June 22, 1982, file photo, Britain's Prince Charles, Prince of Wales, and wife Princess Diana take home their newborn son Prince William, as they leave St. Mary's Hospital in London. Princess Diana’s caftan-like outfit hid the post-childbirth tummy bump that is normal for any new mom. 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.
