If you're searching for a relaxed and at the same time stylish outfit, consider pairing a blue crew-neck sweater with olive chinos. The whole outfit comes together perfectly if you complement this look with a pair of slip-on sneakers. This one is a great option when it comes to putting together a well-coordinated outfit for unpredictable fall weather. This getup proves that well into your 30s you have a vast array of sartorial options.
