I've often had this thought about the origin of the tie, and especially of its evolution from collar-closing strip of silk to vertical element as the design of jackets became more open and the placket was exposed. Despite my much-derided opinions on contrast and rule-breaking, I've always hated exposed plackets. I'd suggest a light cashmere or merino sweater with a bow tie.
And I always tell my laundress to stretch the placket, but she informs me that referring to her as "my laundress" will result in divorce proceedings.
I take it this mean you have broken the old rule about not having unnatural relations with the staff?
Well you solicit advise and comments, so here is one of a different very "butler" nature:
Traditionally the shirt is regarded as part of the underwear and not to be seen. This is taking things a bit far nowadays, but if you want to wear a (self tied, of course) bow tie, it is a very becoming idea to do that only when either wearing a DB (which you never unbutton) or a SB with a waistcoat.
I came to think of this watcing you post, and it became even more obvious if one zoom in on your shirt front, as the placket has been very badly laundered/ironed, leaving it full of "bumps"!
Tell your laundress to stretch the placket with one hand, and press with the other - problem solved!
Your cuffs are always very nicely done by the way :-)
Interesting! I had initially considered an emerald green sweater vest, but decided that might be too many different colors. I will definitely keep this in mind next time I choose a bow tie.
Unfortunately, I am my own laundress -- my wife doesn't iron. So I will pay careful attention to the placket next time and try giving it a stretch! I can usually achieve a pretty good press on my shirts, but sometimes these thick Oxford cloth shirts can pucker on the seams a little.
