Lady Amelia Windsor wows in lace slip dress as she attends Earth Day dinner in London

Lady Amelia Windsor looked stylishly chic as she attended an Earth Day dinner - which featured other high society attendees, including socialite Delphi Primrose.

The granddaughter of Prince Edward, Duke of Kent, was effortlessly elegant in a  strappy black slip dress, which had lace detailing at the neckline and fell to her ankles.

The 28-year-old paired her ensemble with a hot pink satin shoulder bag and some comfortable fuchsia-coloured flats for the event in Marylebone, London on Monday.

She wore her golden blonde tresses up in a messy, yet styled, bun and fastened it in place with a vibrant yellow scrunchie. 

Lady Amelia sported a natural look, only wearing a touch of glowy makeup and opting for chunky gold hoops, a heart-pendant necklace and a beaded bracelet that said 'Love' on it.

The model was at the One Tree Planted Earth Day Dinner at The BoTree hotel with Zoe Zimmer, Delphi Primrose and Andrea Cheong. 

The US-based charity works with partners from around the world to help the environment by tackling deforestation and encouraging biodiversity. 

Since 2014, they have planted over 135.5 million trees with 378 partners across 82 countries in North America, Latin America, Africa, Asia, Europe and the Pacific.

Similar to King Charles, Lady Amelia is passionate about nature and planting. She is working on a wildflower plot that will be exhibited at the Chelsea Flower Show this year. 

Amelia - once dubbed the most beautiful member of the Royal Family – is also trying her hand at writing about gardening.

Today, she appeared to be  in high spirits as she put her arms around her friends and smiled for snaps with them. 

Elsewhere socialite Delphi, 20, looked stylish in a satin green frock paired with black and gold cowboy boots and a glitzy silver back. 

She stacked multiple gold necklaces and opted for gold and green drop-earrings, donning glamorous makeup, with bronze eyeshadow, pink lipstick and eyeliner.

She is the daughter of Lord Dalmeny, who is the chairman of auctioneers Sotheby’s in the UK.

Her family seat is the impressive Gothic Revival mansion Dalmeny House, to the west of Edinburgh, and which is currently home to Delphi’s grandparents the 7th Earl and Countess of Rosebery. 

Delphi has appeared on several covers of Tatler magazine as the next 'It girl' after she amassed millions of views on TikTok. 

Like Amelia, she finally signed with well-known modelling agency Storm in 2018, after being repeatedly scouted.
