Please share your thoughts on whether workwear, and this is assuming you work in an office type environment and don't have to interact with clients face to face, should be policed by your company through a set dress code.

Is it really necessary to have one when you don't need to visit with customers?

If so, why do you think so? I've heard some say that if you don't dress in a business like manner, for example you wear jeans and not a business suit, your work suffers. Do you think that's accurate or that you could work just as well whether you're in denim or a designer suit?

Maybe a more casual uniform would be a good compromise for a company's office staff, like khakis and polo shirts.

Any ideas on what should be the case would be appreciated. Thanks!
