Nobody does casual tailoring quite like Boglioli, and the Italian company has constructed this version of its unstructured Dover blazer from cotton-piqué for a completely relaxed feel. Unlined through the body, it is suitable to be worn in the warmest climates over a T-shirt, but will look equally suave over a merino wool sweater. Pop the collar to show the contrasting underside. Shown here with a Loro Piana shirt and trousers, Charvet pocket square and John Lobb shoes.
