Make a field jacket and a charcoal vertical striped suit your outfit choice if you're aiming for a neat, stylish getup. If you need to easily play down this getup with one single item, why not go for a pair of high top sneakers? On not so cold afternoons, wear this summer-to-fall outfit and look absolutely amazing. That's the look for a guy in his thirties to convey you've got what it takes to succeed.
