Simple loin cloth wraps made of denim with adjustable nylon straps and a velcro closure.
Waist - They will adjust approximately 5-7 inches from the waist measurement you provide. You want to measure with a measuring tape around where you normally have pants hang along your hip, or across your stomach at the navel, which ever you prefer.
Hip - Measuring around the hip area will help keep the kilt from being too snug around your hips, rear, and the jewels.
Length - This measurement is usually taken by kneeling. You want to measure from your side, not down the front of your leg. Measure from where you took your waist measurement down to the floor. This makes the kilt length about mid knee.
