The Scottish kilt is a garment that is wrapped around the wearer's body at the natural waist (between the lowest rib and the hip) starting from one side (usually the wearer's left), around the front and back and across the front again to the opposite side. The fastenings consist of straps and buckles on both ends.
A kilt covers the body from the waist down to the centre of the knees. The overlapping layers in front are called "aprons" and are flat; the single layer of fabric around the sides and back is pleated.
A kilt pin is fastened to the front apron on the free corner (but is not passed through the layer below, as its function is to add weight). Underwear may or may not be worn, as the wearer prefers, although tradition has it that a "true Scotsman" should wear nothing under his kilt.
