It looks like the LA sun is clearly agreeing with Meghan Markle, who looked simply radiant in a video while giving a speech to young girls around the world. 

Appearing as part of the virtual 2020 Girl Up Leadership Summit, Markle delivered an empowering speech on race and gender inequality in what was her first public speaking job since stepping down as a working member of the Royal Family. 

For the occasion, Meghan chose a stunning blue silk top by Adam Lippes, a celebrated New York designer that came of age in Ralph Lauren and Oscar de la Renta and favours the clean lines of American sportswear.

The pin-tucked silk crepe de chine top flattered the Duchess's elegant frame, with a sleeveless cut and flowing trapeze cut. While we couldn't see it in the video, the top features an elegant pleated back. 

The vivid cobalt blue shade was particularly striking on Meghan, who looked luminous with a gentle glow to her skin from the LA sun. She paired it with her Cartier 'Love' Yellow Gold Bracelet, which she's worn on many occasions.

Originally costing $990, the top was reduced to $148 in the sale, but it's already sold out on most retail sites. 

It was a welcome reminder of what the Duchess brought to royal fashion, choosing elegant cuts and sharp tailoring over soft fabrics, and always shining in bright, fresh colours. 

Meghan also debuted longer, sleek hair, with her locks blow-dried straight and hanging down past her shoulders. Her haircut was typically fresh and modern, with long layers cut to frame her face. With a flick of black eyeliner and a nude lip, the Duchess looked sophisticated and elegant.

Speaking in the video, she said: "Your generation is often referred to as digital natives, and you understand that our online world has the power to affirm and support as much as it does to harm. We are not meant to be breaking each other down; we are meant to be building each other up.

"So use your voice both on and offline to do just that – build each other up, support each other."

Referring to recent movements for equality, both online and in public, Meghan encouraged the young people to keep working. "I say to you, keep challenging, keep pushing, make them a little uncomfortable. Because it's only in that discomfort that we actually create the conditions to reimagine our standards, our policies, and our leadership."

Central to her speech was the need for compassion, both for yourself and for the people you're challenging. "Compassion doesn't mean we shouldn’t feel anger and outrage when we see blatant injustice all around us—of course we should", she said. "But I challenge you to broaden that feeling. The Dalai Lama famously said, 'Compassion is the radicalism of our time.'"

Referring to her own experience of overcoming negativity, she said: "We are not meant to be breaking each other down. Build each other up, support each other. 

"There will always be negative voices and sometimes those voices can appear to be outsized, and sometimes they can appear to be painfully loud. You can and will use your own voices to drown out the noise. Because that's what it is—just noise. 

"But your voices are those of truth. And hope. And your voices can and should be much louder."
