The star, who unveiled her Stella MCCartney x Goop capsule collection earlier this month (Sep13), is now collaborating with Williamson to create a Swarovski crystal-embellished sweatshirt, which will be sold on the actress' lifestyle website, Goop.
The British designer says, "I am happy to be able to bring this exclusive piece to Goop. It's such an effortless piece for autumn, the crystal embroidered neckline adds a twist to the classic off-duty sweatshirt adding a decadent touch to a wardrobe staple."
The olive-coloured sweater is retailing at $845 (£563).
The Oscar-winning actress has previously teamed up with brands Chinti & Parker, Melissa Odabash and MiH Jeans to create limited-edition pieces to be sold exclusively on Goop.
