When you start looking to custom print shirts you will find yourself in a maze trying to figure out which size best fits you. There is no standard unit of measurement.
Some T shirt brands will have their measurements in cm while others will have their in inches. Some will show their Tee shirt sizes in XS, S, M, L, XL, 2XL etc. While others show their sizes in sz 2, sz3, sz 4, etc. US brands have a different measuring scale compared to Australia. In fact each country sizing chart varies. A medium shirt purchased from the US will be totally different in size from one purchased from India for example. Something to keep in mind.
It gets very tricky because you will need to navigate between 4 different types of measurements when ordering. I find my customers need help especially when ordering sizes for men, women and children as each group quite often show sizes in different measurements.
