When I first became interested in this tee, it was so my son and I could have matching ones. From the website, the pictures modeled a woman and their child in the photos. So when I ordered, I ordered my sizing for womans. There was no picture of a man wearing this shirt. I am unsure if there was a specification that the sizing was unisex but it is. The shirt is huge and I had to give it to my husband who I am unsure will wear it because he said the fabric is so thin that it's see-through. I am disappointed that it didn't work out.
