I love overcoats. Personally, I think to complete the 'businessman' look, you need a good overcoat. It needs to be the correct length: just so it reaches the kneecaps (if you're short like me) and a subtle yet powerful colour like navy, charcoal or, my personal favourite, black.
My Nº. 1 recommended jacket for this fall, the Lightweight Nylon Military Jacket in Ivy - by Frank and Oak. I recently bought this and wear it every chance I get. I'm 6'5" and the Large is a perfect fit. The fabric has a great feel, the construction is excellent, and the ivy color is really cool. At $125 it's a great deal for a jacket that you will never want to take off. See more from @frankandoak #mensfashion #fallouterwear #nattyguy
