One of the best ways to style such a timeless menswear piece as a black trenchcoat is to pair it with a light blue dress shirt. Balance out your ensemble with more laid-back shoes, like these black leather brogue boots. So so as you can see, it's a killer, not to mention spring-ready, look to have in your transitional rotation. If you're often not sure how to dress maturely but also look fashionable, this combination is a never-failing option.
