I've ignored every single rendition of the "glove-toque flow chart" because, as much as I respect CWO-CPO1s...I also understand they don't authorize dress policy. Advise, enforce? Certainly...
I use this example sometimes to demonstrate dress importance; the RNoAF guards at Andøya main gate. Pony tail with a braid, down past the middle of his back. Beard, also long and "braided" or whatever the proper term is for "not all lose and blowin' in the wind". I think he had ear ring(s) in as well.
His chest rig was squared away. Weapons was spotless. His beret was shaped well and squared away. Uniform was clean, boots were shone. He was fit, he was professional, he was confident and composed.
I remember thinking "they're getting it right".
