[2] The traditional perahan varies according to the region of Afghanistan with some ending at the knees and others midway between the calf and the feet (in which case small slits are created).
[8] Further, the traditional perahan is wide but fits closer to the body down to the waist and then is loose and full down to the knees[9] (thereby flaring out).
[2] The tunban therefore uses a lot of material so that it gathers around the waist and folds around the legs.
The length of the dress is to the knee and the wearer has the option of choosing the lower part to be in circle or square in design.
The popular embroidered perahan tunban for men is the type worn in Kandahar.
