 Here are two ways to do business casual. Option one, start with some navy chinos paired with a classic striped button up. Both of these items are from Charles Tierwitt. The fit is great and the chinos are non-iron, extremely comfortable and come in a range of colors and fits. I'll add a belt, some light brown derbies, and then to complete the look, a gray tweed herringbone sport coat. Proof that keeping it simple is never a bad decision. Option two, same shirt, same shoes, but swapping the navy chinos for a khaki pair. Instead of a sport coat to keep it a little more casual, I'm going with this Charles Tierwitt Navy Merino wool zip up cardigan. It's a more relaxed look, but still appropriate for a business casual situation.
