The clothes you require employees to wear should be determined by the nature of your business and the amount of face time those employees spend with prospects and customers. Industries whose employees function behind the lines, with little or no client contact, may adopt a less restrictive dress code policy. In contrast, sales-oriented operations and financial organizations adopt to a more formal standard. Salespeople and employees who manage money represent the face of an organization, conveying first impressions that may make or break a business relationship. Information technology professionals or individuals who configure networks and install hardware tend to be viewed as front-line warriors. Without their work, many client operations would slow or stop altogether. As such, most customers expect such employees to don blue-collar attire. Jeans, work boots, and flannels hold out as perfectly acceptable clothing for this group. On the other hand, financial consultancies and accounting firms should adopt a policy mandating business attire and strictly define what constitutes that mode of dress. Casual or business casual Fridays seem to be a readily accepted norm in almost any industry. Clothes say a lot about a person, and dress codes project an image to your customers. Know your business and those customers. Determining what to wear and what not to wear should flow easily from that knowledge.
