A grey trenchcoat and a grey crew-neck t-shirt combined together are a match made in heaven for those dressers who prefer casually sleek styles. Add charcoal athletic shoes to the equation to infuse a dose of stylish effortlessness into this look. As the weather starts to improve, it's time to get rid of those heavy winter layers and choose something lighter, like this ensemble here. This combo demonstrates how to stay fashionable as you reach your 30s.
