Opt for a dark green crew-neck sweater and navy jeans to pull together a truly dapper and modern-looking laid-back outfit. Finishing with dark brown leather casual boots is a fail-safe way to add some extra fanciness to this outfit. When it's one of those bleak autumn days, what better to brighten things up than a on-trend getup like this one? Ideal if you're in search of some amazingly inspiring over-40 style.
