Jill Stuart’s fall muse was the modern, aristocratic Brit, “like Stella Tennant,” the designer said before her show. She thus sent out a charming display of fun-to-wear party frocks and dashing dinner suits. These came in a range of exclusive fabrics she spent a lot of time developing, and her tenacity paid off. A flippy skirt in ribbed raffia looked like variegated ponyskin but was actually surprisingly lightweight. Dresses, which comprised the bulk of the collection, were in laser-cut wool or fashioned from intricate wool lace, sometimes trimmed with foil and flocking. Given the intensity of the textures, Stuart was wise to keep her silhouettes straightforward. The results should appeal to women who, like Tennant, wear their chic with a shot of cool.
