Meghan Markle reveals her wedding ceremony day 'one thing blue'

With days to go till we sit down to look at the hotly-anticipated documentary concerning the royal household, Queen of the World, we have simply realized an undeniably lovable element about Meghan Markle's wedding ceremony costume.

Speaking in her first televised sit-down interview since turning into a royal, the Duchess of Sussex opens up about her iconic Givenchy wedding ceremony robe, revealing precisely what the 'one thing blue' was in her outfit.

Running her fingertips throughout the costume' veil – that includes embroidered flowers to signify all of the international locations of the Commonwealth – and the costume itself, Meghan asks the interviewer: "Somewhere in right here, there is a piece... Did you see it? The piece of blue material that is stitched inside?"

When the interviewer admits she will't see something, the 37-year-old royal reveals the 'one thing blue' is "material from the costume that I wore on our first date", referring to her first romantic evening out with Prince Harry.

On studying the never-before-heard element, the interviewer gushes, "that is about probably the most romantic factor I've ever heard", prompting the Duchess to giggle.

When the couple introduced their royal engagement in November 2017, Markle opened up about their first date.

"It was a blind date," Meghan defined, earlier than Harry admitted he was in awe at seeing her.

"I used to be superbly stunned once I walked into that room and noticed her. I used to be like, 'Okay, effectively I'll need to up my sport'," he revealed.

And up his sport he did.

Queen of the World airs on Tuesday, September 25 at 9.15pm on ITV.
