Meghan, the Duchess of Sussex, put her stamp on British Vogue's September issue and is now putting her stamp on a fashion collection.

The 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.

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.

It was Meghan's work as patron of Smart Works that first inspired her to meet with Edward Enninful, the editor-in-chief of British Vogue

After their first meeting in January, Meghan asked to guest edit an issue. The September issue that she co-edited with Enninful will hit newsstands in the U.K. and be available for digital download on Friday, Aug. 2.

The cover of the issue, titled "Forces for Change," features a grid of 15 influential women, with one square of the grid embossed in a shiny, mirror-like effect to reflect the reader.

Meghan's first public sign of support for Smart Works came last January when she chose it as the first charity she visited after her first royal patronages were announced.

During that first visit, she met with clients and volunteers and helped a woman style an outfit for a new job.

After that first visit, Meghan paid a series of "quiet visits" over the last year to Smart Works that inspired her to create the capsule collection, according to Buckingham Palace.

"Throughout her visits she noticed that while the donations were plentiful, they were also notably a combination of mismatched items and colours which weren't always the right stylistic choices or sizes that didn't necessarily 'suit' the job at hand: to make a woman feel confident and inspired as she walked into her job interview," the palace wrote on Instagram, adding the collection will include "the key workwear essentials [the women of Smart Works] need as they enter into the workplace."

Smart Works took to social media to thank Duchess Meghan for her support.

"Our Smart Works family is flourishing under the Duchess's patronage," the organization's CEO Kate Stephens said in a statement. "We have dressed more women than ever before, and we have just had our best ever July, helping 27% more women across the U.K. than the same time last year."

"We want to help more women find their way to a Smart Works centre so that they may, in the words of the Duchess, be ready to take on the world, get a job and transform their lives," she said.
