A good warm-weather layer should add shape without weighing an outfit down. Our women’s casual summer jackets are chosen with exactly that in mind, bringing together relaxed cuts, breathable natural fabrics and the ease of one-size dressing. Made in Italy and designed to sit comfortably over dresses, tops and loose trousers, these jackets are the pieces you reach for on cooler mornings, breezy afternoons and evenings when you want an extra layer without losing that airy summer feel. Cotton and linen give them a fresh, dry handle, while softer silhouettes keep the overall look easy to wear. This is the kind of plus-size casual jacket collection that makes layering feel simple.
