must-have ! XL Set Up Loungewear Pajamas Navy Shirt Men's Short Sleeve T-shirt

I purchased this for my husband, but it was too small when he tried it on, so I'm unfortunately letting it go.
It's listed as XL, but the size is equivalent to M-L.
It's only been tried on, so I've marked it as "prefer latest."
There are no tags.
