There is new dress code at my office, effective today. The organization has allowed for jeans to be worn Monday to Thursday. Of course, there are rules in regards to this jeans rule but that is not what I want to talk about today.
The thing is, I am not a fan of this change at all. I strongly encourage you to wear business casual even if your organization allows jeans. Perception/image goes a long way and the way you dress can have an influence on how you are perceived at the office. Employees may believe that dressing professionally indicates to coworkers that they are motivated, skilled, hardworking, and serious about their workplace responsibilities (Peluchette & Karl, 2006).
There is the old rule of thumb that says dress for the job you want, not the job you have. As a young sales professional, this truly applies as you likely aspire to be in a client facing role in the future. If you do, you can kiss your jeans goodbye.
