Finally we have a president who knows how to tie his tie!
Note the handsomely made pleat under the half-windsor knot. That is how it should be done, people! A tie is not meant to be smooth-fronted. The pleat, like the lapel button-hole that is there to allow the jacket to be closed up to the neck, is a holdover from when a tie was more like a cravat. Mind you, it helps to have a tie of this quality that will accept the knot correctly. Kudos on the pattern, too.
The trick is, as you tighten the knot, to pull the long end to one side, which will form the pleat correctly. Also to be noted is the perfect fit of the shirt collar and the exact amount of cuff showing. Plus the exquisitely tailored suit in a handsome dark blue.
