This off-duty combo of a crew-neck t-shirt and blue jeans is perfect when you need to look great but have no extra time to plan out an outfit. For times when this look is too much, play it down by rocking a pair of brown work boots. As you can see, this combo is a really wonderful choice, especially for in-between weather, when the mercury is getting lower. This combo shows that as a 20-something gent, you have a wide range of outfit options.
