This combo of a black crew-neck sweater and a light blue dress shirt is a must-try casually neat outfit for any modern gentleman. If you wish to instantly smarten up this outfit with a pair of shoes, why not introduce a pair of dark brown suede loafers to your look? A perfect example of transeasonal style, this look is ideal when warmer days are here. So if you're on the lookout for a good-looking and age-appropriate combination, this one is great.
