I got two cool looking work shirts from Land's End, on sale for $19.99 each. They were originally $44. I got black and navy blue--the fabric is strong but smooth and the pockets have hidden double pockets under the button flaps.
I just checked and they have some remaining in very large sizes. Navy, khaki and charcoal.
These shirts will last 30 years because they are so sturdy and well made. Even the elbows are double lined. And yes, they are very butch looking.:fastdraq:

If you buy from Dxl or destinations xl which is a big men's store, it's pricey but worth it on undershirts and underwear even shirts. Only issue i have is length, its hard to find a 28 or 29 inseam.
