The style of business shirts is basically based on French shirts, with beautiful French sleeves. However, depending on the matching dress or formal wear, the collar and placket can be different from the traditional French style. Business shirt cuffs are tight, neckline is tight, collar is stiff. The cuffs of a business shirt must be buttoned to the top, and it would be silly if the top one was not buttoned. Business shirts will not have superfluous embellishments.
