Kaftans were worn by the Ottoman Sultans in the Ottoman Empire. The decorations, including the colours, patterns, ribbons, and buttons, indicated the rank of the person to whom they were presented. From the 14th century through 17th century, textiles with large patterns were used. The decorative patterns on the fabrics became both smaller and brighter in the late 16th and in the 17th centuries. The Topkapi Palace Museum in Istanbul possesses a large collection of Ottoman kaftans.
