The cockpit is a different story for all the reasons mentioned previously. The pax are expecting to see a certain (very high) level of professionalism coming from the people in there.
I don't recall anyone saying you couldn't ware what you want in the back, but dont expect the JS if you do. In fact, AA changed the rules recently to allow for pretty much anything a passenger would ware, since they didn't want gate agents having to be the ones determining your dress code conformity.
