Marry a navy vertical striped double breasted blazer with navy vertical striped dress pants if you're going for a neat, dapper getup. When in doubt about what to wear on the footwear front, complete your ensemble with a pair of black leather tassel loafers. Naturally, you're looking at a good choice for a boiling hot summertime afternoon. A fail-safe option pairing appropriate for 50-year-old gents.
