You'll be amazed at how easy it is to pull together this refined outfit. Just a dark green fair isle crew-neck sweater and charcoal wool dress pants. If you wish to easily dress down this look with shoes, why not complete your getup with a pair of brown leather brogue boots? You can see this combination is also a perfect example of how to style warm layers in the colder months. Looks like this help welcome the big five-oh with class and confidence.
