Such pieces as a white and black vertical striped dress shirt and navy chinos are the ideal way to introduce some manly refinement into your current off-duty lineup. To bring out a classy side of you, complement your ensemble with dark brown suede monks. With rising temperatures come warmer days and more sunlight and the need for a knockout ensemble just like this one. As you mature into your 30s, you want to start dressing maturely. That's when inspiration like this proves very useful.
