Royals Kate Middleton Steps Out in Her Go-to Coat Dress from Her Wedding Dress Designer Alexander McQueen The royal couple attended the naming ceremony for a research ship is being named after Sir David Attenborough, who Prince William recently interviewed about his work highlighting the importance of the natural world By Stephanie Petit Stephanie Petit Stephanie Petit is a Royals Writer and Reporter at PEOPLE. People Editorial Guidelines Published on September 26, 2019 08:13 AM Share Tweet Pin Email Kate Middleton and Prince William are teaming up for a special occasion — with champagne! While Prince Harry and Meghan Markle continue their royal tour of Africa, Kate and William stepped out together on Thursday to visit attending the naming ceremony of the U.K.’s new polar research ship, the RRS Sir David Attenborough, in Birkenhead. Both Prince William and Sir David Attenborough gave remarks before Kate had the honor of formally naming the ship and smashing a bottle of champagne (from a safe distance away via a button!) against hull. For the occasion, Kate recycled her light blue coat dress by Alexander McQueen (her wedding dress designer!), which she’s worn on several occasions dating back to 2014. She kept the rest of her look simple, wearing black heels and carrying a black clutch by Asprey, with her hair in her signature bouncy blowout. Kate Middleton.

On board, Kate and William met a team of engineers from Cammell Laird who have been involved in the ship’s build, including young apprentices. Kate Middleton.

They then visited the bridge where they will meet the ship’s captains and crew members and hear about the ice-breaking capabilities and navigation systems. Kate Middleton and Prince William.

It made headlines when the Natural Environment Research Council let the internet suggest a name — and the overwhelming winner was “Boaty McBoatface.” (Also in the running were “It’s bloody cold here,” “Usain Bolt,” “Ice Ice Baby” and “Notthetitanic.”) Prince William and Kate Middleton.

Though the NERC opted instead to name the $287 million vessel RRS Sir David Attenborough, it did bestow the silly moniker upon a yellow submarine operating from the ship.

Prince William interviewed Attenborough about his work highlighting the importance of the natural world and the urgent challenges that will face the next generation of environmental leaders at the World Economic Forum earlier this year.
