[villainy vs heroism]

Basically, I've been getting into costume design, and have suddenly developed a big-time appreciation for military uniforms, of the sort prevalent in WWI and II eras (so, not so much modern camo, please). Nothing makes them look as good as anime embelishment, so . . .

Can anyone suggest any animes and mangas that use this same aesthetic?

I'm already aware of Axis Powers Hetalia, Hellsing, and Full Metal Alchemist using these sorts of styles. And while those come from different categories, I'm more concerned with appearance than genre, so feel free to suggest animes from all across the spectrum.

Thanks!
