While it's true that some office dress codes have loosened up a bit, you should still have a few go-to blazers in your wardrobe for things like client lunches and smart-casual events. Tailored from a lightweight basketweave cotton and ramie-blend, this stone-grey unstructured Incotex piece can be easily dressed up or down. It's cut slim, left unlined and has soft shoulders so it layers comfortably and is easy to move in.
