This is
just my opinion....so please take it as that, no more. And I fully understand your concern with not wanting to wear something like hearts and butterflies.
I am not sure I like the idea of camouflaged scrubs, not even for military nursing. I don't know if it's the connotation of war, to which I'm pretty opposed, or what. I just don't know that I like it.
That said, it's up to you and if I were working with you, I wouldn't say anything because camo isn't vulgar or otherwise violating any hospital dress code that I'm aware of. And if I had to choose, I'd go with a camo top vs pants.
But this is all just me, so please listen to others before you decide.
