Why not team a long sleeve shirt with light blue chinos? Both of these pieces are very comfortable and look nice when matched together. Avoid looking too formal by rounding off with a pair of blue athletic shoes. As the weather starts getting warmer, it's time to shed those bulky winter layers and choose something lighter, like this outfit here. Think you can't pull off modern off-duty looks as you step into your 50s? This combination is hard proof of otherwise.
