A company needs a clear uniform policy. The policy can build trust between a company and their employees. The company leaders need to make it clear what the dress code is meant to look like; with somewhat precise details.
You can find different consultants that can create the policy. The whole thing is truly about developing a culture. The culture is meant to be a positive element that can help lead to more overall productivity.
The dress code can also lead to fewer distractions and more overall respect within an office setting.
