Fun t-shirt, new

I ordered several of these t-shirts for a group of photography friends that we go on shoots together. The sizes run small so these couldn’t be used. I included a picture with a tape measure. This shirt is marked a medium but fits like a small. Sleeves are 3/4 length. I don’t remember exact fabric content but was a blend so shouldn’t shrink much. Small discoloration of fabric not a stain. Shirt has never been worn.
