Such items as a crew-neck t-shirt and light blue dress pants are the ideal way to introduce a touch of manly elegance into your day-to-day off-duty lineup. And if you wish to immediately dial down your look with a pair of shoes, add a pair of charcoal slip-on sneakers to the equation. A cool ensemble like this one is just what you need on a super hot hot weather day. Wear this outfit to pull together a more conservative look as a 20-year-old gent.
