Style affectations: cigarette case, pince-nez, hip flask, walking stick.
Should you see a man with a walking stick, seize it and smack him on the hip flask with it.
Number of neckties you
must own: one.
Which one? The black knit tie.
A black knit tie coordinates with jeans and a blazer as well as it does with a French cuffed shirt and a custom-made suit.
Of course, you're better off with a handful, all in silk: a couple of dark solids, a handful of simple diagonal stripes, and one or two natty small-patterned numbers, such as you'd buy at Hermès.
Woven silk ties generally look more luxe than printed silk.
The Moscow theory as applied to necktie acquisition: anytime you see a necktie you like, buy it. If you decide to wait and come back later, it will be gone.
The tie tack is to fashion as the appendix is to anatomy: vestigial.
