Traditionnal bride costume in late Ottoman style. End of 19th or first half of 20th century.
The long dress is named ‘bindallı entari’, and is adorned with silver thread embroidery on velvet.

‘Bindallı entari’ means: ‘robe with thousand branches’, because the decorative motifs on the robe consist mainly of branches with leaves and flowers.

‘Bindallı’ work is a kind of ‘goldwork’, a term used even when the threads are imitation gold, silver, or copper. The metal wires used to make the threads have never been entirely gold; they have always been gold-coated silver (silver-gilt) or cheaper metals, and even then the "gold" often contains a very low percent of real gold. Most metal threads are available in silver and sometimes copper as well as gold; some are available in colors as well.
