For a laid-back ensemble, make a charcoal crew-neck sweater and a crew-neck t-shirt your outfit choice — these items fit really well together. And if you want to easily step up your getup with one single piece, why not complement this ensemble with grey suede loafers? This getup is a savvy pick when spring arrives. This pairing demonstrates that as a man in his 40s, you have a vast array of outfit options.
