The Duchess then made her official return from maternity leave to make a speech outside of Smart Works. She wore two pieces from the collection - the Jigsaw black pants and Misha Nonoo white shirt, as well as giving a sweet nod to her late mother-in-law by wearing Princess Diana's bracelet and butterfly earrings, both of which she's worn before.
The collection – which features a shirt, pants, a blazer, a dress and tote bag – will be on sale for two weeks starting today with one piece donated to Smart Works for every one sold.
Below, the three pieces that are already available to shop. You can't feel guilty when it's for charity, after all.
