Demonstrate that no-one does classic and casual menswear like you by wearing a white polo and charcoal vertical striped dress pants. Add a pair of white low top sneakers to this outfit to avoid looking overdressed. As you can see, this getup is a really good pick, especially for unpredictable fall weather, when the mercury is getting lower. On a mission for dressing ideas for gentlemen in their thirties? This pairing is pretty inspiring.
