This combination of a grey crew-neck t-shirt and olive chinos is definitive proof that a safe casual outfit can still look incredibly sharp. Add brown leather espadrilles and ta-da: this look is complete. Casual outfits for over-40 gentlemen aren't actually that hard, as you can see.
If the setting allows a relaxed ensemble, consider teaming a grey crew-neck t-shirt with olive chinos. White low top sneakers are the glue that will pull this ensemble together. Perfect if you're in search of some amazingly inspiring style for 40-year-old gentlemen.
