Not really. Not at all.

Nazi Germany famously hired top-of-the-line designers like Hugo Boss to create show uniforms that were actually very uncomfortable to wear (I've read that apparently some soldiers couldn't sit down properly wearing them) made from stiff fabrics that do not accomodate the body. They were literally made to look good on camera and create an image of a sexy "badass" and were not worn in everyday life. Also, the on-the-ground soldiers wore entirely different garbs and were oftentimes severely under-equipped.

I think if you want to portray a fascist in a "cool" outfit you always have to keep in mind that it is deliberate, carefully planned propaganda. It isn't by accident that the SS uniform looks like that.

Now, as a writer, I'd say you can do whatever you want, but it's always good to know the historical context of fashion design and the choices that led to clothing looking the way it does!
