Loafer’s are the traveling business women’s best friend. They slip on and off easily when going through security, they are comfortable, and versatile. The sleeker and simpler the design the more formal it is. Also, darker colors are more formal (black being the most formal), and the less of your socks are visible the more formal the look. Loafers look great with jeans and dress pants, as well as with suits when not wearing a necktie. Common loafer variations are monk straps, tasseled decorations, penny loafers, and formal pumps (see below).
