The shoes should match the belt. Greg is wearing a typical Monday outfit, which is usually the most formal of the week, by sporting a 100-percent cotton French blue shirt, tie and gray pleated trousers.
Black shoes complement the outfit.
Be careful not to confuse the French blue with denim. Khakis are true staples of the business-casual wardrobe. Craig sports a great-looking Thursday outfit. The French blue shirt is back, but this time the sleeves rolled up. All these outfits are similar to each other but don't look exactly alike, which saves money.
