Take your casual style up a notch in a navy raincoat and light blue jeans. Take a more relaxed approach with shoes and enter a pair of athletic shoes into the equation. As you can see here, it's super easy to look dapper and stay warm come chillier days, all thanks to outfits like this one.
A navy trenchcoat and light blue jeans combined together are a perfect match. For something more on the casual side to complete your getup, introduce a pair of athletic shoes to the mix. This combination is a really great option, especially for autumn, when the mercury is getting lower.
