A modern, tailored kilt, with its tapered pleats (tapered from seat to waist) is fastened about the body securely enough with the buckles and straps which are provided for that purpose. The kilt belt worn with such kilts is purely decorative during ceremonial use. They are typically fairly wide – between 2 – 1/2 and 3 inches or so – and come in black or brown leather.
Historically, before the advent of the tailored kilt in the late-18th century, some type of belt was necessary in order to secure the kilt about the person and keep it from falling down. It also provided a handy place from which to hang sword, dirk, or pistols. Today the belt, and associated loops on the kilt modern, remains useful for those wearing the kilt in work environments of all kinds.
