The royal baby's first public appearance had a distinctly Australian feel.
The future king was wrapped in a white shawl made from Australian merino wool when Prince William and Kate first showed him off to the world.
Then, just minutes later, he was swaddled in a blanket designed by an Australian mum before being placed in a car capsule and driven home by his proud dad.
The bird-print cotton swaddle was from US-based company aden + anais, whose founder is Aussie mother-of-four Raegan Moya-Jones.
"We are truly grateful and so delighted that the couple chose to debut the prince in aden + anais," she said in a statement to AAP.

"We wish the Duke and Duchess of Cambridge many congratulations on the birth of their son."
Ms Moya-Jones had children after moving to the United States and couldn't find a swaddle like those she remembered from home.
They were either too small, too thick and heavy, too restrictive or too unattractive, the company says on its UK website.
"So Raegan designed a swaddle large enough to be truly useful to mothers - and not just for swaddling but as a stroller cover, nursing shield, tummy time blanket or a burping cloth."
The royal baby - named George Alexander Louis on Wednesday - gave what appeared to be a tiny royal wave from within its Aussie merino shawl when Kate first carried him out of St Mary's Hospital on Tuesday evening.
The shawl was made by a small English family-run company called GH Hurt & Son based in Nottingham.
The delicate creation is similar to one the baby's father, the Duke of Cambridge, had as an infant, which was also made by the firm.
A company spokeswoman on Wednesday told AAP the shawl was made from a blend of Australian Botany Wool and another thread, fine-spun in Italy, that could also be from Down Under.
"We feel honoured that William and Kate have chosen to use our beautiful merino wool shawl and in doing so have continued a tradition for the next generation of royals," GH Hurt & Son said in a statement.
The company experienced a rush of orders for the super-fine merino wool christening shawl, which costs STG45 ($A75), within 20 minutes of the first sighting of the future king.
