Go for a simple but at the same time casually dapper outfit marrying a navy and white horizontal striped crew-neck t-shirt and a teal shirt jacket. Complete this look with a pair of navy suede tassel loafers to immediately step up the classy factor of any look. So when summer is fading away and fall is setting in, you may find this outfit your uniform. A great combo as you transition into the next stage of your adulthood, your 20s.
