The video posted on her Instagram story was from a shoot that took place in London on Wednesday. A source told ABC News' Royal Contributor Omid Scobie that Meghan wanted to surprise the women from Smart Works and so she showed up once the photo session had already begun.

The upcoming capsule collection of \"workwear essentials\" will benefit Smart Works, a U.K. charity for women for which Meghan is patron. The collection will be available this fall.

The Duchess and Smart Works have more exciting plans in store (watch this space) but for now, we hope you’ll buy this very special copy #ForcesForChange edition of Vogue and be inspired by what you read.

Meghan partnered on the collection with her friend, designer Misha Nonoo, as well as Jigsaw, a British fashion line, and U.K.-based retailers John Lewis & Partners and Marks & Spencer.

For each item purchased from the collection, one item will be shared with a woman at Smart Works, according to the @SussexRoyal Instagram post announcing the collection.

\"Not only does this allow us to be part of each other's story; it reminds us we are in it together,\" Meghan writes in an essay on the collection in the September issue of British Vogue.

ABC News' Katie Kindelan contributed to this report.
