Even if our company didn't have a dress code , I still think people would wear formal clothing to work .   I wouldn't be so sure ... People want to wear what they feel most comfortable in .   Maybe that's true for some positions , but I think the marketing and sales staff would definitely not agree . They dress for success ! You can't go out on a sales call if you are dressed in jeans . It's just not respectful to you client .   I think what you wear is so overrated . I would rather have a down-to-earth , honest and solid sales person than a painted , patent leather , designer suite salesman .   It's not as simple as that . People judge you by your appearance , whether you like it or not . So dressing professional is being professional . The image that you portray to others is so important in business . It's your image and how others perceive you that makes the difference between landing or losing a sale .   Maybe you're right , but I'll take my sneakers and jeans any day !
