Originally a length of woolen tartan? cloth 1.5 m in width and up to 4 m in length. Worn with a wide belt and over the left shoulder this was the 'big kilt' or the Breacan, the Feileadh Bhreacain or the Feileadh Mor. The current garment is more similiar to the Leine Croich, a knee-length garmet of leather, linen or canvas, heavily pleated and quilted as protection.
the modern kilt is called the Feileadh Beg, or little kilt, designed for ordinary wear and so made of tartan or tweed, box-pleated or knife-pleated with the lower edges reaching not lower than the centre of the knee-cap. It dates from around the mid-18th Century, replacing the more simple belted plaid. The kilt is for men only.
It was made illegal to wear the Kilt in Scotland by the Dress Act of 1747, repealed in 1783.
