The Duchess of Sussex has made a surprise appearance at a fashion photoshoot for the charity Smart Works in a behind-the-scenes video shared on the Sussex Royal Instagram account on Wednesday.

In the clip, the Duchess is seen helping coordinate the shoot for the capsule collection she is spearheading in partnership with the women's organisation.

Smart Works, one of her first patronages, helps women, many from disadvantaged backgrounds, get interview-ready by providing them with a new outfit and coaching from a team of volunteer mentors.

The video is captioned: "Sneak peek at the new Smart Works charity capsule collection shoot, ahead of the autumn launch.

"An initiative supporting the Smart Works collective which will equip women entering the work force with the key work wear essentials they need… Coming soon."
