The khaki belt does provide an easy horizontal transitional line between a top and skirt. This look can be achieved by simply placing the belt where the waist of the skirt meets the shirt. After the belt is snuggly buckled, the remaining excess strap can be wrapped around the wearer and tucked neatly into the secured portion of the belt. The result should be a clean seamless khaki line with no protruding ends. Often I prefer to turn the buckle to the back of the ensemble. The neutral transitional line is also effective when wearing summer sundresses and comes to full maturation when balanced with another neutral element of some sort (such as nude shoes).
Another alternative to adding more milage to your bland belt and/or cuff straps is to color them with fabric paint; I prefer a neon pink or lime green. The same concept may be applied to neutral colored shirt dress belts.
