A v-neck sweater and a red long sleeve shirt are both versatile menswear essentials that will integrate really well within your current wardrobe. Our favorite of a great number of ways to complement this look is with a pair of black rain boots. As you can see here, it's very easy to look seriously stylish and stay warm when chillier days are here, all thanks to combos like this one. This getup shows that looking fashionable as you turn 30 is not that hard.
