This sophisticated combo of a brown suit and a black sweater vest is undoubtedly a statement-maker. To give your overall look a more laid-back feel, complement your outfit with a pair of beige suede tassel loafers. This getup is a really nice idea, especially for fall, when the temps are dropping. As you're getting to your 30s, you want to start dressing more maturely. That's when outfits like this are a life saver.
