A kilt is fastened and secured using a combination of straps, buckles, and closure systems that hold the garment in place around the waist. Traditional kilts typically use leather straps and metal buckles positioned on the sides, allowing the inner and outer aprons to overlap and be adjusted for a secure fit. Modern kilts may incorporate additional or alternative closures such as snaps, Velcro, or other fastening systems for convenience and flexibility. The waistband supports the structure of the kilt, while the fastening system ensures it remains properly positioned during movement and wear.
