If you prefer a more relaxed approach to fashion, why not consider teaming a long sleeve shirt with beige chinos? And if you wish to easily step up this outfit with shoes, complete your ensemble with a pair of brown derby shoes. If you're looking for an easy-to-transition ensemble, this one fits the bill. As you're getting to your 30s, you want to start dressing like an adult man. In this case, combos like this become very relevant.
