A brown shearling jacket and a tank are the kind of a no-brainer casual look that you so awfully need when you have no time. Clueless about how to finish this look? Wear brown leather brogue boots to lift it up. Laid-back looks for young gents aren't actually that hard, as you can see here.
Consider pairing a brown shearling jacket with a tank to assemble a casually cool ensemble. A pair of black canvas low top sneakers integrates seamlessly within a great deal of combos. And if we're talking casual dressing ideas for 30-something men, this combination looks cool on most men.
