In a corporate environment, appearance matters a lot. This is especially true when dealing with high-profile clients. Employees in the roles of sales representatives, account managers, and coordinators face big-time clients almost every day. That is why you would want them to look their best to impress the people they meet at all times. You want potential customers to see your brand in a positive light to make them want to do business with you. You might even want them to wear branded lanyards with your company name for a polished and uniform look.
