Zimmerli Response: The Richelieu rib is a very delicate fabric and each shirt is cut one by one.
The shrinkage of the fabric has a lot do with the humidity during the production.
It would help me a lot, if you could give me more information about the length after washing.
We generally suggest the customer to stretch the wet shirt in order to get more length after washing procedure.
