The mismatch of the size grid and the poor quality of the T-shirt.
I ordered a T-shirt in size M (men's) as a gift. The T-shirt was too small. I thought that I probably made a mistake with the size. After one!!! The hand-washed T-shirt has shrunk to a size XS for women. The print quality is good.
If possible, measure the T-shirt before ordering and take a larger size, taking into account that it will sit down after washing
