IRREGULAR can be explained as having one or more of the following minor flaws:
Thread Pull
Dirt Mark
Cut in the label
Subtle shade difference between buttons
None of these flaws are very obvious. The flaws on the front of the item are less apparent than those on the back. Most marks, such as dirt, will often fade or come out completely after washing.
Please note: Irregular items generally have one or two of these flaws - Not all of them.
