What is interesting is the essential difference in the underlying social stuff.
Female officers can't decorate like that.
Why? Need to give impression serious, means business, don't try any shit with me fellas. I'm a police officer who happens to be female. I have authority and if you forget that police officer first then you're screwed.
How many female officers who out sharp end, would choose to have fancy nails and strong makeup?
I met an ex SO19 woman once.
I'm not sure that painted nails and makeup would go without MASSIVE (more interesting than her skills etc) media and public commentary about the nails (negative).
She quit because of constant daily sexist vile bullying.
And trust me she was nails. Just who you want doing that sort of thing.
