Kate Middleton in fits of giggles as she tries on a lifejacket at Royal Navy base in Somerset

The Princess of Wales rocked business chic as she arrived at a naval base in Somerset this morning/afternoon – before erupting in giggles as she tried on a lifejacket during an exercise.

Kate, 41, donned a £549 black blazer from Holland Cooper which she has worn previously, with gold button detailing, paired with trousers and £650 black pumps with a thick heel from Gianvito Rossi as she visited the Royal Navy Air Station in Yeovilton.

The Princess, who is commodore-in-chief of the Fleet Air Arm as of last month, styled her long, thick brunette locks in bouncy blow-dried waves, with her new 70s-style fringe framing her face perfectly. Showcasing her natural beauty, the mother-of-three kept make up simple with a touch of blush, a nude lip and a bronze eye and she accessorised with white topaz Kiki McDonough teardrop earrings.

While visiting an aircraft hangar, the mother-of-three fell about laughing while trying on an emergency lifejacket and inflating it as she wore it around her neck. Elsewhere in her visit, she chatted with personnel in the air traffic control tower.

Pictured trying on an inconspicuous-looking camouflage lifejacket, the Princess beamed but looked a little apprehensive as she prepared to inflate the device.

As she pulled on the toggle, she closed her eyes and winced as the device inflated quickly and with force, just as it would in an emergency situation.

Appearing a little taken aback by the fast inflation, Princess Kate burst into a fit of giggles, before staff aided her in removing the lifejacket.

Upon arrival at the naval base, the Princess was pictured shaking hands with staff members in the tower, where staff work hard to ensure the safe operation of RNAS Yeovilton.

While there, she had the chance to communicate with the crew members onboard an airborne Wildcat flight. 

She was then shown around the hangar where she met personnel to discuss the different operations that take place within the Fleet Air Arm. 

Last month, the King appointed Princess Kate as commodore-in-chief of the Fleet Air Arm, a position previously held by Prince Andrew. 

Her solo visit comes as her husband, Prince William, prepares to fly to New York later this afternoon where he has a busy week of engagements in New York Climate Week, ahead of events surrounding this year’s Earthshot Prize.

After landing in Newark Airport in the city this evening, the Prince of Wales, 41, will visit the Billion Oyster Project, which is running an initiative to restore oyster reefs in the New York Harbour.

The project collaborates with local schools and brings in pupils to solve the challenges faced in the battle for climate conservation. 

Following this visit, the Prince will head to the UN General Assembly where he is due to meet with António Guterres, the UN Secretary General. 

Tomorrow, William will attend the Earthshot Prize Innovation Summit ahead of this year’s Earthshot Prize ceremony, which will take place in November.
