It belonged to Nikitsyn Vasily Mikhailovich (1885-1943), a native of Nikitsy village, Pustozerskaya volost.
The kosovorotka or Russian shirt got its name because of the collar feature: the shirt slit is on the side (usually on the left), not in the front as on modern shirts.
At the end of the 19th century, the Russian shirt was the basis of any costume and more often it was worn with a vest. It was sewed from linen, silk and satin. There were two types of kosovorotoka shirts: a working and festive one, depending on the decoration richness. Later they were replaced by wraparound shirts with a turndown collar.
