I bought this shirt over the summer (yes, it's taken me this long to figure it out) while in Las Vegas. Unfortunately, I didn't heed my wife's advice and try it on before I bought it. The shirt is just a little too big for me, so I am looking to sell it.
It is their size 5 (medium in Canada), and has only ever been put on once to see how it fits. All of the tags are still attached and I have the receipt in case you are concerned with authenticity.
The price for this shirt is
$40, firm. I live and work in the deep SE, and will need you to meet me near here to pick up the shirt.
