Renapd had one during the old PoserWorld/FairyWoods days called "Grandad Shirt", you may contact her to see if it is now a PoserWorld product or where she may have it posted these days. And as hauksdottir pointed out the RDNA western clothes may fit that style too. (actually Renapd's shirt looks like my old teen-aged shirts from the early 70's ;)
