Today, at about 2:15 pm EST (that's 7:15 pm GMT), Kate Middleton and Prince William stepped out of the Lindo Wing at St. Mary's Hospital in London with their new baby son—still unnamed for the time being—in tow. Perhaps in honor of the new Prince of Cambridge, both proud parents wore pale blue; a polka-dotted Jenny Packham dress paired with nude wedge heels (!) for Kate, an oxford shirt with rolled-up sleeves for Wills. In addition to being downright pretty, however, the Duchess' outfit choice is also symbolic; back when Princess Diana and Prince Charles left St. Mary's with their newborn baby William back in 1982, Diana too opted for a blue polka-dotted number (pictured below).

"He's got her looks, thankfully," Prince William joked as he greeted the throngs of press, adding, "he's got a lot more [hair] than I do!" Speaking of hair, Kate's looked predictably flawless—her hairdresser reportedly paid her a visit at the hospital earlier today to prep her for her much-photographed departure.

Congratulations to the happy, healthy family—now, let's get working on that name, shall we?
