Kate Middleton christens 'Boaty McBoatface' wearing $15k outfit

The Duke and Duchess of Cambridge visited Birkenhead today, for the naming ceremony of the ship the public voted to be named ‘Boaty McBoatface’.

The research vessel, which has officially been named after Sir David Attenborough, will enable world-leading research to be carried out in Antarctica and the Arctic over the next three decades.

Their Royal Highnesses met a team of engineers from Cammell Laird who have been involved in the ship’s build, including young apprentices.

The couple were accompanied by Sir David Attenborough, who joined them as they visited the flight deck to meet scientists who demonstrated how the state-of-the-art equipment is used to carry out research while out at sea.

The ceremony saw the Duchess, who is the ship’s sponsor, smash a bottle of Champagne on the ship’s hull - a tradition which dates back hundreds of years.

For the occasion, Kate opted to rewear her customised coat dress from Alexander McQueen.

It is a clear favourite for the Duchess, who first debuted the coat back in 2014 when she attended a remembrance service for New Zealand’s war dead.

Made from wool crepe fabric with a rayon and acetate blend, the coat is belted, features deep utility pockets and includes hidden buttons and snaps. Although Kate’s version has been altered as it falls below the knee, is collared and includes a peplum pocket feature.

The coat costs a purse-bursting $4,282 and has, unsurprisingly, completely sold out.

To complete the look, the Duchess styled her coat with a $3,378 navy Asprey 1781 Pochette clutch bag, $721 block heel court shoes by Emmy London and $6,849 white gold and diamond drop earrings by Mappin & Webb.

The total cost of the Duchess’ outfit is estimated at a whopping $15,515
