A navy denim shirt looks so good when worn with a v-neck t-shirt in a laid-back look. To introduce some extra classiness to this ensemble, complement your look with dark brown leather brogues. Many people mistakenly assume that just because it is snowing outside you have to sacrifice good style, but that's just not true, and this ensemble is proof. As you turn 30, you want to start dressing more maturely. If that's the case, getups like this come in very handy.
