RockyTop - providing detailed measurements, rather than simply the labelled size, would prevent any surprise about the shirt's dimensions. Of course this is a learning for future transactions. If the buyer is going to provide negative feedback, then it's probably better to avoid that by offering some sort of accommodation, up to a full refund.
Check out my eBay auction:
Brooks Brothers, Solid White
This is the classic shirt in beefy cotton oxford: it is not non-iron (thank, goodness)
Original Polo Shirt Button Down Collar
Extra Slim Fit
Current size is 15-1/2 x 32
Made in USA
100% American Supima Cotton
I thought I was slim until I put this on--it's a very slim fit!
The shirt is in very good condition; it's been worn only several times.
