Personally I love everything about this combo of scarf and pinstripe suit but don't let yourself get bogged down in the specifics.
This is one of those great abstract inspiration images - "dramatic scarf for a serious suit"
I think it shows how a simple ,but well chosen, accessory can liven up a typical 9 to 5 suit.
A men's version of "day into evening"
The idea would work just as well with contrasty, bold colors and can be just inspiring to both men and women.
