Sarah Ferguson, 58, was in Gothenburg, Sweden today for The Perfect World Foundations event.
The red-haired Duchess attended the event alongside Sir David Attenborough, matching the stunning surroundings in a vibrant outfit.
The event was taking place in the botanical gardens of Gothenburg, with David Attenborough picking up an award during the annual dinner.
Complementing the bright floral displays in the botanical garden, Fergie wore a vibrant yellow blouse for the occasion.
The summery blouse was slightly sheer, featuring long, floaty sleeves and pocket detailing.
Wearing a few buttons undone, the Duchess showed off her elegant gold pendant necklace.
The tunic came to below her hips, cinched in at the waist and sitting loosely above a simple, black pleated skirt.
Perfect for rambling through the gardens, Fergie wore a classic pair of black suede loafers with gold buckle detailing.
She wore her striking hair down and in natural curls, keeping her makeup to a minimum for the awards dinner.
Showing off how much she loves nature, Fergie was pictured taking snaps of the vibrant flowers and strolling around excitably in the gardens.
In one photo the Duchess was seen scooping down to pick up an apple from the floor.
The event was in aid of the charity The Perfect World Foundation, which is an international organisation that focuses on conservation.
The Gothenburg-Based organisation aims to protect animals and nature, with Sir David Attenborough picking up an award today.
During the event in the botanical gardens, David was seen planting trees and showing off his green fingers.
The Duchess of York is a big advocate for many charities herself, including conservation and children’s charities.
Sarah is no doubt preparing for the upcoming wedding of her youngest daughter, Princess Eugenie.
The former wife of Prince Andrew is said to still live in the Royal Lodge with her ex-husband.
However, their divorce in 1996 was said to cause a rift within the Royal Family. Now a source has claimed, via magazine Vanity Fair, that Princess Eugenie wants her mum to have a big role in her wedding.
They told the publication: “Sarah is being very hands-on, but in a great way, and Eugenie wants her mum to be a big part of it all and will make sure Sarah is included in every aspect. “Her feeling is the other royals will have to get on with it.”

However the couple remain on good terms, even living together in the Royal Lodge from 2008 until Sarah moved to a ski chalet in Switzerland they bought together in 2015.
Sarah has written children’s books for many years, her first being a series about Budgie The Helicopter in the early 90s.
She has also been the US spokeswoman for WeightWatchers after famously battling her weight over the years.
