Figure A--Not only is the monochromatic look among the hottest this season, but it truly takes the guesswork out of picking a coordinating outfit. No complaint from men here. If he would like to vary a standard blue-on-blue look, for instance, an option would be to go pattern-on-pattern (see photo). In this case, a very slight, small pattern works well with a tie that carries a larger pattern. The patterns are different, but only slightly, so that it doesn't jar the eye.
Figure B--For a stronger monochromatic look, go with a darker shirt and a textured tie. The crinkled fabric gives the appearance of a pattern, when actually the texture is the pattern. This look enables the wearer to stay within the fashion and yet add some subtle flair at the same time.
Figure C--A high-polished leather slip-on shoe can either be worn conservatively or with a more casual look. With dark pants, stay in the dark, charcoal or navy blue realm when it comes to socks. A belt should have clean, smooth lines with an understated belt buckle. Of course, the shoes and belt should be the same color.
