Shirt with standup collar

Since ancient times, underwear has been the basis of clothing for both men and women. Medieval shirts made by us are based on commonly known shirt patterns, the shape of which changed slightly throughout the Middle Ages.
Depending on the period, they were more or less fitted and differed slightly in details, such as the form of the neckline, etc.

This model has a delicate stand-up collar. It was widely used in the late 15th century and was worn under a doublet.
This type of historical underwear is common in iconography, especially in Italian painting of the late 15th century.
