HBO SOPRANOS longsleeve thermal shirt vintage NEW UNWORN promo

Description

Thermal shirt is in new, never worn, never washed condition.  Fabric is of a waffle / honeycomb type.
Despite the collar tag claiming the size is "M" / Medium, the actual pit-to-pit across the chest width is only 17 inches (as pictured in photo  3 ), so it's even smaller than a modern "Small".
Was it meant to be tight for warmth?  Have no idea if it will stretch to fit, it has not been tried on.  All photos are original and show the actual shirt being sold.  To see close-up details, please click on the individual photos
