This single-breasted blazer lends itself to formal settings, but can be dressed down for casual events too.
Crafted from soft Pima cotton, it's tailored on a relaxed-fitting block and shaped with curved sleeves for an unstructured finish. It features welt pockets, cuff plackets and a vent at the back. Style it with the matching trousers.
