Every man should own at least one pair of classic, versatile dress shoes that can be worn in a variety of different situations. The most common and versatile style of dress shoe is the Oxford. Oxfords are characterized by their closed lacing system, which creates a sleek and formal look. They are typically made of leather and are available in a range of colors, from classic black and brown to more modern shades like burgundy and navy. Another style of dress shoes that every man should consider owning is the Derby, which are similar to Oxfords, but have an open lacing system, which makes them slightly less formal (though you can dress Derbies up or down).
