WW2 US Nurse Uniform

[flicflac]

Hi all, I am relatively new to reenacting and am struggling to work out what I need as my Class A uniform and am continually getting more confused, especially when I don't yet understand the lingo. I am hoping to reenact a nurse in late 1944 in Europe. I have recently acquired a nurses enlisted jacket (not that I knew it was enlisted but was later told) and so I am wondering whether a US Nurse could be wearing an enlisted jacket while deployed? Also, what hat would accompany the Class A uniform, would it be a garrison or peaked cap, I have seen reenactors wear both but I would like to know which is more historically accurate for the late 1944 period.

If anyone could help or offer alternative sources of information it would be greatly appreciated.
