I've been a fan of KingSize products for a while, particularly their tee shirts.  I am 6'2" and prefer my tee shirts to fit a bit long, with the sleeve length around the elbow.  In the past I have ordered from KingSize and the size was just right and the quality has been great...good material, and the fabric and size held up during repeated washings.

Unfortunately, I've not had the same positive results from this particular purchase.  The material is thin, and after one wash (cold water, I might add) the shirt is really too small for me now.  I regret the purchase, and suggest you try something else.  It makes me wonder if KingSize has switched vendors/manufacturers, because quality-wise their tee shirts aren't what they used to be.
