The uniforms were unpopular with the cast. Martin Landau was unhappy with the new uniform he was given for this episode, as this note on his script reveals.
I don't want to concern myself on the set with the wardrobe - it looks good if I am standing up straight and not moving about - but when and after I do - every wrinkle in the undershirt shows through.
(my stomach is pretty hard now) but even so, if I bend over now it accentuates my stomach and makes me look fatter than I am. It's not flattering - I don't want to spend any time making the wardrobe look good. I'd rather it made me look good - without concern. I've got enough to think about - if all my concentration goes to that everything else will go down the drain - it takes too much of my concern - and makes me uncomfortable.
So I'd rather wear the two old ones and keep after them, mending as we go - taking care of them, sewing them, until they fall off my back - for they are better and we use these two as back up costumes, reserve wardrobe! For I look better, overall, in the older ones!
