Trouble with wearing bow ties to work is that, come the festve period, or boxing formal do time, work mates ask you to tie theirs so that they can untie tham after the dinner!!
( both guys had self tiers, but with an adjustable and releasable catch)
I did try to point out that that only works if you retie them afterwards.
Pretied bows are, of course, even worse than massmarket nylon shirts.
