Comfort Fit Cotton Dress Shirt

This is a very attractive shirt and I included it on a short list to purchase today. I realize this is heavily marked down from an artificially inflated price, even so, how can a merchant offer a dress shirt without sleeve length? I'm completely gobsmacked by the silliness of the omission. Unless it is being promoted as a one-size sleeve-length fits-all, no matter if you are 5'6" or 6'5". There is no provision for an inquiry, so maybe a review will get someone minding the store to address the neglect.
