A harrington jacket and a blue long sleeve shirt matched together are a match made in heaven for those dressers who prefer casually stylish styles. Give a dressed-down twist to an otherwise all-too-safe getup by finishing with brown leather work boots. Can you see how extremely easy it is to look seriously stylish and stay comfortable when fall arrives, all thanks to looks like this? And if we're talking casual style for 50-something guys, this ensemble looks cool on most gents.
