According to the regulations of the army, military uniforms can be changed if they don't fit, but they can't be changed without permission (including changing the size and length)! However, the military uniforms now look much better than in the past. When I was in military school, I was still wearing big pants, which was ugly. I even secretly changed it! Ha ha! But I didn't let the captain find out. Maybe I turned a blind eye when I found out!
