What she wore: how Kate Middleton honoured Diana as she introduced her third child to the world
Kate Middleton understands more than anyone the relevance of a picture.
While most new parents get to bask in their newborn joy for at least a few days, with only close friends and immediate family meeting the new arrival, Kate and Prince William have a more formal affair, 'the big reveal' on the steps of St Mary's Hospital just hours after welcoming their third child.
As they did with Prince George in 2013, Princess Charlotte in 2015 and now with their new prince, all eyes were on Kate mere hours after being in labour, in particular on her choice of outfit.
With George, it was a polka dot blue and white Jenny Packham dress, believed to be an homage to William's mother, the late Princess Diana, who wore a similar polka dot shift dress when she introduced her eldest son to the world.
It's clear that the young royals understand the importance of nostalgia - we were treated to those adorable pictures of George, clasping on to his father in order to be the first family member to meet his new little sister three years ago, mirroring the adorable photos of William holding hands with his nanny Barbara Barnes to meet Harry for the first time in 1984.
Next is the hair and makeup, Kate naturally has her personal hairstylist come into the hospital in order to give style her hair in a bouncy blowdry and a makeup artist on hand to help her look picture ready.
Through the years, Kate has changed up her hair with brief experimentations with a fringe and a four inch chop last year, but as always with her pregnancies, it's back to her signature mid-length bounce.
At their third child, the experience is old hat to them, but wherever Kate goes, the fashion police follow.
In 2013, she was hailed as 'brave' and 'normal' because her bump was still visible (it was less than a day after she'd given birth) - critics hid under the guise of 'brave', women saw someone they could relate to. The second time around, she wore a yellow floral piece by the same designer.
For her third, she wore another dress by Packham, this time a red shift dress with white lace collar detail, another tribute to Diana, who wore a near identical number when she introduced Harry to the world on the same steps of the hospital 34 years ago.
