Why not consider pairing a bomber jacket with beige cargo pants? Both of these items are totally comfortable and will look great when married together. If in doubt as to what to wear when it comes to shoes, add a pair of beige canvas low top sneakers to the mix. A good, less conservative pairing for 30-something Millennial gentlemen.
For an outfit that's pared-down but can be styled in a myriad of different ways, pair a bomber jacket with beige cargo pants. Take this outfit a whole other path with a pair of navy and white athletic shoes. Relaxed combos for stylish 30-something Millennial men aren't actually that hard, as you can see.
This combo of a bomber jacket and beige cargo pants is hard proof that a simple off-duty look can still look really dapper. And if you need to easily kick up your getup with one piece, introduce black suede casual boots to this look. This combination shows how gentlemen in their 30s slay in the style department.
