Defense Secretary Mark Esper announced that service members are now allowed to wear their PT gear while shopping at base exchanges. This is provided the ‘attire is clean, serviceable and in good condition and appropriately modest’. However, the memo released that “Secretaries of the Military Departments are authorized to make exceptions to this policy for Service members based on mission requirements and the need to maintain good order and discipline.”
