In a newly-released behind-the-scenes video, Meghan Markle wears this chic button down by Frank & Eileen

On Wednesday, the Duchess of Sussex shared some behind-the-scenes snippets of her highly-anticipated Smart Works capsule of work-appropriate attire in two Instagram Story videos.

With the ‘70s hit “Lovely Day” playing as the soundtrack, the clips show the Duchess partaking in a photoshoot, proudly promoting her collection of women’s workwear essentials, which is set to launch in the fall.

The collection is a collaborative effort between the Duchess and brands Marks & Spencer, Misha Nonoo, John Lewis and Jigsaw to help support Smart Works, a U.K.-based charity which helps unemployed women to enter the workforce through fashion and confidence.

The clips also show a giddy Markle surprising and hugging models as they enter and smiling from the sidelines. And as royals aficionados who total swoon over rare footage of an overly excited and happy Duchess, we also can’t getter over Markle’s office-inspired ensemble.

On-set, Markle wore a $300 CAD Frank & Eileen soft blue pinstripe button-down blouse which she paired with skinny jeans and nude point-toe heels. Despite the steep price tag, the chic button-down has already sold out at a number of retailers.

This isn’t the first time she’s worn this outfit — during the royal tour of Australia, she wore the same famous Frank & Eileen shirt in white.

SHOP IT: $304, Neiman Marcus (sold out)

While that exact shirt seems to be sold out at most retailers, Revolve still has a number of the same style shirts in stock — including this very similar pinstripe one, which is on sale!
