If you're on a mission for a casual but also seriously stylish ensemble, wear a brown crew-neck sweater and khaki chinos. And if you want to effortlessly dress down your outfit with one item, complement this ensemble with white canvas low top sneakers. This getup is a savvy idea if you're piecing together an amazing transition look. Think middle-aged men can't pull off modern casual outfits? This pairing is hard proof of otherwise.
