What is the difference between inside and outside labels?
Custom inside and outside shirt labels are one way you can brand your products. Either one costs an extra $2.50 per shirt and can be a maximum of 3"x3". Note that inside and outside labels can't both be printed on one shirt - it's one or the other.
Inside labels are printed on the inside of the garment and require the removal of the original manufacturer's tag. They're only available for shirts with tear-away tags - see your choices here. An inside label graphic must include the country of manufacturing origin, original garment size, and care instructions. You can download inside label guidelines here.
Outside labels are printed on the outside of the garment underneath the collar. They're available for all shirts except racerbacks.
