This combination of a grey horizontal striped crew-neck t-shirt and brown cargo pants is on the casual side but is also sharp and incredibly stylish. On the shoe front, this outfit is complemented nicely with black and white canvas high top sneakers. So as you can see, it's extremely easy to look stylish and stay comfortable when colder weather hits, all thanks to outfits like this. A safe bet combo proper for men in their 30s who like casual dressing.
