Apart from the effect it has on the people you interact with it also has an effect on how you shut down after work. Taking off the more formal work attire for more casual home clothes creates a more relaxed individual at home.
My company is a Jeans and T-Shirt company in general but I prefer something a little more formal. A client can walk in at any time and I will be properly dressed for a meeting. This also has the added benefit of people who don't work with you often assume you are competent and tend to listen when you talk where the Jeans and T-shirt guys need to be a little more convincing...
