UWN - I was thinking you could use a clothing converter (but you'd need to buy it and install it) such as PhilC's Wardrobe Wizard.  That's the only one I use so I can say it will work.  The link I gave you for the uniforms - yeah, I think the trousers and boots are worked as one piece.  As for Poser Club, they have 100++ items free now, so a lot of scrolling through pages.  I recall German officer and maybe US army officer jackets but that's about it.
