Make it a cinch.

Though belts have not made quite as big an impact in the promotional products industry as they did at New York's Fall Fashion Week this past February, there are still plenty of ways to work the waist into a wearables program. To allow end-users to accommodate a belt if desired, go for a woven shirt that has darts on both the front and the back, so it nips in at the waist. Or, for a less-literal approach, define waists with apparel that has color blocking down its sides, or that comes with a drawcord at the waist.
