Companies recognize that the type of clothing their employees wear affects the image they're promoting to their customers or clients. For example, employees of a surf shop may be outfitted in tank-tops and shorts all year round, while the law firm next door requires strictly suits and ties. Generally, employers set their dress codes according to customer contact, industry standards, and the general culture of the company. What's appropriate for one company may not be for another. Dress codes can also vary from job-to-job within a company. Some employees of an organization may be required to wear uniforms or special safety clothing, while other employees who have a great deal of contact with the public may be subject to the standards of business attire. Employers will generally describe their dress code requirements in a written policy. This policy should include examples of acceptable clothing as well as clearly state what's not appropriate. Companies might also choose to go into specifics, regarding skirt lengths, jewelry, or facial hair. If employees violate the dress code, perhaps by dressing sloppily or wearing clothing with potentially offensive images or words, they may face disciplinary action that can include verbal warnings as well as suspension.
