How do I measure the width of the Viking Linen Tunic?

The width-measurement is measured from side to side of the product as opposed to the full way around, which would be the full circumference.
The width is half of what the full circumference would be. 

If for example a Viking Linen Tunic has a width of 24” Inches across the chest, then the full chest circumference of the product would be 48” Inches.
When measuring a Viking Linen Tunic, the width is measured from side to side under the arms, across the chest.
