Apparently WFB has been cited in this debate before.

And, from a reader:

My brother insists – perhaps correctly – that the real issue is whether a button-down collar should be worn with a suit, and that the answer to that is clearly “no.” Although I am presently violating that ordinance, I believe he is correct. Save the button-down collars for blazer-and-slacks days.
Now, back to work.

Update: As a great many readers have brought to my attention, the picture of John Bolton immediately below my original post, shows the man wearing a button down collar. ‘Nuff said.
