The Peranakan retained most of their ethnic and religious origins (such as ancestor worship), but assimilated the language and culture of the Malays. The Nyonya's clothing was identical to that of the native Malay's: baju panjang (long dress), batik sarung (batik wrap-around skirt) and kerongsang (brooch). Beaded slippers called Kasut Manek were a hand-made made with much skill and patience: strung, beaded and sewn onto canvas with tiny faceted glass beads from Bohemia (present-day Czech Republic). In modern times, glass beads from Japan are preferred. Traditional kasut manek design often have European floral subjects, with colors influenced by Peranakan porcelain and batik sarongs. They were made onto flats or bedroom slippers. But from the 1930s, modern shapes became popular and heels were added.
