The bow tie does not have to be a boring single color, it can be checked, striped or even polka dotted. Experiment with what you love and even go out of your comfort zone with this style that has proved porpular among the fashion savvy men.
Remember the sweater has to be V-neck to maximise on the full effect of this fashion statement, otherwise anything goes in terms of the color of both the sweater and the bowtie.
