I agree with the 'no' as well.
Its a very good 'period colourisation' effort though. The grey colour of the nurses apron is a question mark for me as well, most of the originals I've seen in collections and museum's (and original German photos) have all been white not grey, plus the seersucker blue striping on her blouse looks a little too pale as well, compared to the very black look to the StG44?
I agree.
For fun, and with nothing much else to do, I just scanned through about 40 original images of German nurses, lol.
One factor, and one anyone who has served in any capacity will notice is, their uniforms were starched and ironed, likely every night, this has an effect, even on a shirt at the end of a hard day, you can still see the starched ironing effect - the OP's image - has not starched her shirt ever.
Also, and this is a little more personal - and I choose my worlds delicately.
All of the shirts were fitted on the larger side, as are most uniforms (unless you're in the Spanish legion), the women wearing them were also likely living on a low protein diet, so the shirts would appear even less fitted as the war progressed. The rifle puts this image as a fairly late war image.
Even the rare images of large framed nurses show their uniforms to be looser fitting than the one in the image.
Also did not see another image of a shirt with those neat little collar tabs.
I'm not an expert on uniforms especially not nurses uniforms, but thought I'd add my 2 cents.
