The hunting shirt is a type of coarse shirt that was the uniform in many colonial armies during the latter part of the 18th century.
The modern men's shirt was originally an undergarment.
The guayabera is an embroidered shirt with four pockets.
In the early 19th century shirts had removable collars and cuffs that could be washed separately without having to wash the entire shirt. This was one way of ensuring the shirt lasted longer.
