If you're facing a fashion situation where comfort is key, try teaming an olive military jacket with a navy crew-neck sweater. Put a different spin on an otherwise traditional ensemble by slipping into a pair of white canvas low top sneakers. Keep this combination in your front hall wardrobe when warmer days are here, and rest assured, you'll save time getting dressed on more than one morning. When it comes to casual style tips for mature guys, this look is ideal.
