Scottish Kilt Belt
The Kilt Belts 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. It is common to see belts worn with a Prince Charlie jacket and waistcoat in evening dress (generally among wearers of hired outfits at weddings etc.). This is regarded as incorrect among traditionalists. The proper reason being that the belt buckle is obscured by the waistcoat and that the line of the tailoring is disrupted by the bulk of the belt, thus making the effect of the costume less flattering to the wearer.
