This off-duty combination of a v-neck sweater and white jeans is a foolproof option when you need to look casually stylish but have no extra time to dress up. Throw a pair of brown chelsea boots in the mix to kick things up to the next level. There's no nicer way to spice up a dull autumn afternoon than an on-trend look like this one. This pairing is a vivid example men in their fifties can still very well slay in the fashion department.
