I wouldn't be surprised if these were actually models. Notice the second from right has different shoes and the last has loose hair. A photo that would become public like this was most likely staged for propaganda use. Mark, do you have any NK female naval officers in skirts?
I did notice the different shoes on the second woman from the right. I also noticed that it looks like she has been eating good in the neighborhood. I love the look on the face on the woman on the far right. Those shoes almost look like pole shoes.
The last one looks like her hat is held on with hairpins to look like a pill box.
The photo is either staged, or there is lots of sexual harassment in the People's military and the girls know it is more advantageous to look as good as possible than to do pushups in the mud.
One thing for sure is that the NK military likes big, tall hats. Nobody has bigger, taller hats than NK generals. "We have big hats and nuclear weapons!!!" I guess when you are 5' nothing, you need to add a couple of inches to your head to look more intimidating to the enemy.
