If you're looking for a relaxed but also dapper getup, try teaming a green crew-neck t-shirt with beige chinos. When it comes to shoes, this outfit is complemented perfectly with grey canvas slip-on sneakers. So as you can see, this look is a really savvy idea, especially for transeasonal weather, when the temps are getting lower. Casual looks for gents over 30 aren't actually that hard, as you see here.
