Pairing a navy and white print crew-neck t-shirt and a grey suit is a fail-safe way to inject your styling lineup with some effortless sophistication. If you want to break out of the mold a little, complement this outfit with a pair of black and white athletic shoes. Naturally, you're looking at a wonderful option for a baking hot day. As you reach your 30s, you want to start dressing more like a mature gentleman. That's when combos like this are a real lifesaver.
