It's not that radical, you know. I am a 2nd Ltn and when I end the work, I'm off duty and that is my own decision what I wear. They actually don't have any rights to say what to wear off duty. They can try but it is not right. Might be different in the states. Most officers change civilian clothes at the garrison before they leave home. (And I really think most of them wears much more untidy clothes than me... but hey, trousers are a common OK!)
