A navy waistcoat and beige dress pants are absolute mainstays if you're planning an elegant wardrobe that holds to the highest sartorial standards. In the footwear department, go for something on the casual end of the spectrum and round off this getup with a pair of dark brown suede tassel loafers. This one will play especially nice come summertime. Combinations like this go a long way towards building your style as a 20-something gent.
