A blue shawl cardigan and a long sleeve shirt matched together are the perfect combo for those dressers who prefer casually sleek outfits. For something more on the sophisticated end to finish your getup, grab a pair of brown leather derby shoes. So if you're on a mission for a look that's sharp but also totally spring-ready, this one is great. Dressed like this, any gent in his 40s is guaranteed to put the younger crowd to shame.
