Epic Militaria Replica WW2 German M43 Field Grey Wool Tunic (38 inch) https://www.amazon.com/dp/B07M9Z79RK/ref=cm_sw_r_cp_apa_i_mpVSDbGMKHHTP

I think the M43 is as close to it as you'll get. Her uniform isnt necessarily 100% accurate. None of them are. But this is a really close shirt. Hope I was helpful.
