The tag in the shirt that runs large is glued in with "ProDry Pique" and "Made in China" on the tag. The seam drapes several inches over the arm/shoulder. The ones with the sewn in tag appear to fit. The shoulder seams align with the end of the shoulder/arm. I have several (purchased on sale) that are horizontal contrasting stripes with white (lisle?)collar that have no shoulder seam, but the sleeve ends about and inch just above the elbow. Thanks for the information and help.
That makes sense, the shirt with the heat pressed tag is an older model, with the old cut. They are still lingering in stock at some retailers but not many.
