This casual combo of an olive raincoat and a white crew-neck t-shirt couldn't possibly come across as anything other than ridiculously dapper. Inject this outfit with some extra elegance by slipping into a pair of dark brown leather loafers. Keep this getup in your front hall wardrobe when spring comes, and we guarantee you'll save time crafting what to wear on more than one occasion. And if we're talking dressing ideas for 50-something guys, this getup looks nice on almost any guy.
