This is how you do summer smart without looking like you tried too hard. Cut from a crisp, breathable cotton ticking stripe, this jacket has a soft, unstructured feel that completely bypasses any stiff formality. The half-lining keeps things incredibly light, meaning you won't melt the second the sun comes out at an outdoor wedding or during a warm-weather commute. We love the subtle details here, from the very light shoulder padding that gives just enough shape, to the functioning cuffs and classic two-button fastening. It sits comfortably in that sweet spot between relaxed and sharp. Throw it over a clean white polo and some relaxed trousers for an easy weekend lunch, or pair it with the matching trousers to go full summer suit. It’s the kind of throw-on piece that makes you look instantly put together.
