It is based on wool jersey underwear from the 1940s.
At that time, underwear was not very stretchy and most of the underwear was open at the front, so-called Henley neck.
Considering the fact that it will be worn as a nurse, the opening is shifted to the side instead of the center front, and the opening is designed so that it does not overlap.
It is assumed that it was tucked in. The back of the neck was reinforced with the same fabric from the back.
The material is jersey, which is characterized by its natural unevenness.
It is tightly knitted using yarn that recreates the uneven texture of the era when it was not possible to spin beautiful straight yarn.
The cuffs are made with a double-layered circular rib, the same as the undershirts from the 1910s.
