Want to infuse your menswear collection with some casual cool? Try pairing a tobacco bomber jacket with a sweatshirt. Introduce white canvas low top sneakers to the equation to infuse a dose of stylish nonchalance into your ensemble. So as you can see here, it's a sharp, not to mention season-appropriate, look to keep in your seasonal sartorial collection. And if we're talking casual outfit ideas for gentlemen in their thirties, this combo is perfect.
