This combo of a long sleeve t-shirt and sports shorts is hard proof that a safe off-duty ensemble can still be really interesting. Rounding off with a pair of white leather low top sneakers is an effortless way to introduce some extra fanciness to this outfit. So as you can see, it's a killer, not to mention season-appropriate, combo to have in your transitional wardrobe. All in all, perfect for a gent in his 20s.
