Consider teaming a shirt jacket with a red crew-neck sweater if you're aiming for a proper, stylish ensemble. Add brown suede tassel loafers to the mix to make the outfit slightly classier. When it comes to dressing for fall, nothing beats a neat getup that will keep you comfortable and looking your best. As a gentleman in his thirties, you want to start dressing with more polish. In this case, combos like this are ideal as inspo.
