Thrifted this Lands End OCBD that has some possibilities. I'm gonna put a saved search for it on the bay. It is a LE "Direct Merchants" "Trim fit" that is made in Hong Kong. Collar points are 3.25" Don't have a protractor so I'm not gonna do the angle thing. It has an unlined collar, but has lined sleeve cuffs. I care more about the collar than the sleeves, lol. Fabric is 100% cotton and this one feels nice and soft.
Don't know how old this is b/c the LE ones I've checked out at Sears have seriously short collar points. Could be wrong, but the Sears ones are all non-iron. I'm partial to slim fits. Carry on.
