Another component of making a good impression is your appearance. While it is true that many companies have adopted "business casual" dress codes, it is important to realize how you dress is a reflection of the image you project to your colleagues. Before you start, inquire with HR, your boss or your co-workers as to what is appropriate. Even if the dress environment is casual, always dress professionally. If the dress code at your workplace is business casual, it is a good idea to keep some dress clothes at the office for unexpected meetings with clients or high-level management.

Appearance also extends to your workstation. Keep your desk neat and well organized. Demonstrate that you are a professional. Never display objects, photos or calendars that might be considered inappropriate. Your company might have a policy regarding what can displayed. For example, the company might only allow photos of company products to be hung on walls or partitions. If you're not sure, inquire at HR or ask your supervisor.
