And no, its not Gareth Pugh.
When HRH Prince George Alexander Louis is christened in front of an intimate crowd this week, he will be dressed in a replica, created by the Queens favourite dress designer Angela Kelly, of the famous royal Christening gown worn by 60 royal babies since 1841.
The silk-satin gown, which features cap sleeves and a cotton-lace overlay, is now too fragile for wear and, with its retirement, comes the revelation that its hitherto-unnamed designer was former Embroiderer to the Queen, Janet Sunderland.
The daughter of a coal miner from Falkirk, Sunderlands creation has been worn by every monarch since Edward VII and up to Prince George.
I am very proud to think an ordinary woman from a working class background could have designed such a beautiful robe, Sutherlands great-great-great niece, Patricia Perry, told The Sunday Times.
I look forward to seeing the replica on Prince George.
Watch the original in action below on Prince Harry; tissues at the ready.
