As with the brogue and chukka, luggage can be worn with both formal and casual outfits. The versatility of loafers has now made them my number three choice. With a sport coat and denim or chinos, loafers look great, even though they should not be worn with a full suit. The leather or suede options here are yours. It's your choice: tassel or penny. Alternatively, the horsebit loafer by Gucci, with its metal strip down the front, is a fantastic option. You will surely look sophisticated wearing it.
