Small changes of pace can add interest to a day's ensemble without resorting to blasphemies like horseshoes on one's necktie. For example, a navy stripe on a white shirt body with a white collar and a blue on white stripe with the shirt body cut so that the stripe is horizontal. The latter is a favorite because only a bit of shirt is visible in a jacket's vee opening behind the (hopefully solid) necktie, making the effect quite subtle.
The shirts in the photo were made by Joe Hemrajani from Albini's David & John Anderson cloth. They have wide spread collars and turnback cuffs.
