Since re-defining the menswear landscape in the late-1990s, Mr Raf Simons has constantly championed unexpected details that set his designs apart. These streamlined black wool trousers, which are crafted in Belgium, seem like a classic piece of lightweight tailoring but, upon closer inspection, are finished with a cobalt-blue lining that allows the cuffs to be turned up for a flash of colour. We'll be wearing ours with the matching blazer and a pair of black leather Derby shoes. Shown here with a Maison Martin Margiela shirt and pouch , Raf Simons blazer and shoes .
