In mid-19th century Siam; both men and women wore wore similar hairstyles; with the head shaved except for a round tuft on the crown which was spiked like a brush. Both sexes also wore mid-length trousers; or 'pha nung'; which were supported by a belt or tied in a knot. Middle and upper-class women generally wore a sarong or cloth over their left shoulder to cover their breast; leaving their right arm free. Before this time; the midriff and chest were usually left exposed with tattoos decorating the torso.
