allows women to either embrace OR reject that gendered look. It's THEIR choice. Isn't that the whole point? Giving women choices over their appearance? Their bodies? IF they want to embrace traditional genders, what's the problem with that? If they don't, what's the problem with that?
Nothing about that choice affects order, unity or equality. As for "uniformity," there are multiple different types of work uniforms, dress uniforms, even physical fitness uniform options. I spent 22 years in the Army and plenty of times I saw people wearing different uniforms for dress events based on personal preference. I never bought the mess dress even though I was an O5 because I thought it looked like a waiter's uniform. I preferred the Blues. Other field grades liked and wore the mess dress. And back when we still had the green's, you saw up to three different types of uniforms at a formal function. (which is probably the same thing you see now that they have the "pinks and greens."
So, no to "uniformity" as well.
Dress uniforms are the epitome of "style clothing." And even then, the women's uniforms of all types have different styling from the men. Why? Breasts. You can't put pockets on a woman's chest. And you can't have the same cut for women and men for fit purposes. So even when the uniforms are "the same," they ain't the same. Women's bodies are different from men. So this mythical exact sameness you are looking for doesn't exist, and it shouldn't exist. Equal does not equal same.
If this was a situation where women were required to dress one way ("feminine" ) then I'd be the first to say, that's bullshit. But they aren't. They have choices. Sorry but there's zero wrong with that.
