This black Jil Sander X Browns 50 pinstripe button-up blazer features notched lapels, a front button opening, flap pockets, long sleeves and an elongated shape. This piece is a part of a capsule collection that celebrates 50 years of Browns. 'It is not easy to dress well', said Jil Sander - which might possibly be the most effective example of self-endorsement of all time.
