True coats reaching to the knee also take several forms. These are little used nowadays. The küläjä, made of twill or velvet, is tailored at the waist, where the flaring skirt is gathered; the straight sleeves are complete but open at the armpits. There are no buttons, but both sides of the straight front opening, the cuffs, and hem are trimmed with gold lace and a deep border of floral embroidery. The katibi corresponds to the čäpkän in having open sleeves with äḷčäk, but closes above the flared skirt with a button at the waist, and may be trimmed with fur at the collar. Sometimes the čuḵa, a coat with elbow-length sleeves, was worn; the baḵari was similar, but usually shorter, with no buttons, quilted inside, and often trimmed lavishly with gold lace and gilt embroidery. A läbbadä was even shorter, reaching barely below the waist, with the rounded hip projections and side vents, short sleeves, and an open front tied at the waist; it was also quilted inside and richly trimmed. The ešmäk is very similar, but lined with fur, whereas the kürdü, also fur-lined, is simply an open, sleeveless waistcoat. Woolen socks (jorab; Pers. jūrāb) are knitted with a characteristically sharp fold all round the foot, either ankle or calf length, and in a wide variety of colorful motifs. The typical footwear, before the advent of mass-produced shoes, was an open-heeled slipper (bašmaq) with a sole in the shape of a figure 8, the front heavily embroidered or covered with beadwork ending in an upturned curl. Boots (uzun boḡaz čäkmä) had low heels and uppers of tooled leather or embroidered broadcloth. It is the headscarf (kalaḡay, Pers. kalāḡī), made from specially woven silks, that is the most persistent of traditional garments, sometimes worn over a low (6 cm) flat-topped skullcap ( araqčın ), almost covered with gold embroidery, or alternatively a small bonnet (täsäk). Formerly a tube-like hood (čutqu) could be worn to cover both the head and plaits.
