My longtime friend from Spain, asked me the same question. He just got a important job and wants to make a good impression, but the only problem is thats he.s the type of guy that wears sporty things. So he asked me this: "I hate business casual; I never know what to wear. Can you suggest three or four can't-miss wardrobe items to keep things simple?"
One: Get a soft-shouldered cotton sports jacket. I buy them whenever I see them. They’re pliable, comfy, and easy to pack. They do the job of a sweater but look dressier and have lots of pockets.
Two: Cashmere sweaters, especially V-necks. Can’t have enough of those. With a nice shirt it goes perfectly. Three: Good chinos or sporty flat-fronts are a must.
