When the weather can't decide between chilly mornings and warm afternoons, a lightweight blazer becomes the ultimate layering piece. Especially for anyone heading back into the office or refreshing their work wardrobe. Beyond function, the right blazer has a way of making every outfit look intentional. Even a simple combination of jeans, a T-shirt, and sneakers feels instantly more polished with a tailored layer on top. Fit plays a major role here.
