People Editorial Guidelines Published on September 4, 2019 01:48 PM Share Tweet Pin Email Meghan Markle is making her official return to royal duties after maternity leave! The Duchess of Sussex will step out next Thursday, Sept. 12, to launch the capsule collection of women’s workwear she created with her designer friend Misha Nonoo. The outing marks her first official work engagement since she and Prince Harry welcomed their first child, a son they named Archie Harrison, on May 6, making her return to royal duties just over four months after Archie’s birth. The clothing line will benefit her patronage Smart Works, a charity that helps women find employment with coaching tips and professional attire for their job interviews. For every item bought during the sale of the collection, one will be donated to Smart Works. “When you walk into a Smart Works space you’re met with racks of clothing and an array of bags and shoes,” Meghan wrote in the September issue of British Vogue, which she guest edited. “Sometimes, however, it can be a potpourri of mismatched sizes and colors, not always the right stylistic choices or range of sizes.” Samir Hussein/WireImage “To help with this, I asked Marks & Spencer, John Lewis & Partners, Jigsaw and my friends, the designer Mischa Nonoo, if they were willing to design a capsule collection of more classic options for a workwear wardrobe,” she added. “Taking the idea further, many of the brands agreed to use the one-for-one model: for each item purchased by a customer, one is donated to the charity. Not only does this allow us to be part of each other’s story, it reminds us we are in it together.” Meghan Markle.
