Royal Lady Amelia Windsor is selling her designer clothes online for a fraction of the price

Prince Harry and Prince William's cousin, Lady Amelia Windsor, is selling her used clothes online and it's a huge step for circular fashion. 

• Lady Amelia Windsor says her clothes need "new homes and new adventures".
• She is raising money for Cross River Gorilla Project. 
• This follows royal news that Prince Harry and Meghan Markle are called "environmental role models" for only having two children.

Lady Amelia Windsor is raising money for a charity close to her heart by selling used clothes online. 

Prince Harry and Prince William's cousin revealed on Instagram that she's selling her pre-loved goods on Depop and all proceeds will be donated to the Cross River Gorilla Project.

"Had a Spring-ish clean of my wardrobe and selected some items to sell on @depop," she revealed. 

"I've had many a happy time in these pieces but they're now ready for new friends and new adventures. All sales will be going to the charity @crossrivergorilla #ad."

Some of the pieces include a black Dolce and Gabbana crop top, which is listed for £50 and a vintage cardigan which can be snapped up for just £15.

She has also listed items from her wardrobe on fashion rental platform, By Rotation, with 100% of the proceeds going to the Henry Dickens Community Centre.

Who is Lady Amelia Windsor?

Lady Amelia Windsor is the second daughter and youngest child of George Windsor, Earl of St Andrews. Her grandfather is the Duke of Kent—who is first cousin to the Queen. She's one of few royal family members that have tattoos.

She is the youngest of three children and studied French and Italian at Edinburgh University.

The 25-year-old is currently 42nd in line to the British throne and leads a relatively normal life as a model. She was once dubbed Britain's "most beautiful royal".

Amelia (Mel to her friends) has modeled for the likes of Dolce and Gabbana, covered Tatler magazine and walked in numerous London Fashion Week shows.

When she's not modeling, the royal is passionate about promoting eco-conscious fashion. 

"We're all aware of the huge plastic crisis and the effect it's having on our planet," she previously told the Telegraph. 

"Fashion is a key role in that, but then also there are ways we can deal with it.

"Stella McCartney is someone to look up to in that sense, she makes the bigger point in her collection that you can be sustainable and stylish.

"That should be something that everyone looks for when they shop now".

While she's not the most famous member of the royal family, Lady Amelia's decision to raise awareness of platforms such as Depop and the importance of circular fashion is a huge step for sustainable fashion brands.

Is Lady Amelia Windsor the first royal to champion sustainable causes?

Platforms such as Depop encourage consumers to slow the industry down and buy pre-loved to avoid waste and lower consumption. 

Sustainability is a topic championed by other members of the royal family as they continue to highlight climate change and other environmental issues.

In fact, it's the fear of overpopulation that is stopping the Duke and Duchess of Sussex from having a third baby.

The couple—who share a mutual passion for environmental causes—have already made it clear that their daughter, Lilibet Diana Mountbatten-Windsor (born last month) will be their last.

Prince Harry previously told primatologist Dr Jane Goodall that the couple would have “two, maximum” when asked how many children they planned on having.

Citing the reasons behind their decision to stop at two, the Duke said, “I’ve always thought: this place is borrowed. And, surely, being as intelligent as we all are, or as evolved as we all are supposed to be, we should be able to leave something better behind for the next generation."

Prince Harry is not the only royal to go green. Prince Charles has also worked tirelessly to become an environmental leader and drive change.

Having been an environmental activist for decades, the Prince of Wales recently launched his most ambitious project to date—a $7.5billion fund to save the planet.

The future King announced the scheme which forms part of the "Terra Carta" agreement, encouraging businesses to put sustainability at the heart of the business. 

In a rip-roaring speech, Prince Charles said, "Sustainability is a choice. If we make it a part of our core values it will define our purpose, determine our choices and drive our actions.

“Whether as a business, an investor, an asset owner, or as a country, let us choose to make sustainability a core value so that, together, we can build the sustainable and prosperous future our children and grandchildren deserve.”
