It might seem harsh, but it would be the same in our military. Its not the pinkness ,or that she is shopping in slippers, it is that she is in public wearing incorrect uniform.
There are strict rules about how official uniforms are worn, hem levels, cleanliness, hair style, jewelry,which Items must be worn when (like hats) and nothing extra can be added. When you take on a military position you sign up to those rules.
Had she been in civvies, no one would care, but representing the uniform it's still disciplinary matter.
I'm torn really, I feel for her , but it's already daft move, when I wore a uniform I would take it off at the first opportunity, to avoid all the saluting, hat wearing and worrying about ladders in my tights.
