If you have ever lived in Indonesia, Batik shouldn't be something new for you. It is a cloth made by a special wax-resist dyeing technique, and especially associated with the Javanese culture.
Traditionally, Batik is used as a long skirt for women. Until today, it is still used by women in formal occasions (such as a wedding reception), where the batik is combined with a kebaya (a traditional blouse). Btw, I love kebaya!. Batik worn on formal occasions can cost up to millions, depending on the cloth, the design & the technique used to produce it.
Whereas Batik is normally associated with something traditional, in the past year, Batik has been made into modern design clothing, making it a hot & trendy fashion. One brand that I love is Allure, unfortunately it is quite expensive.
It would be a shame for me to write about Batik, without mentioning Ulos, which is the traditional textile of Batak (my ethnicity).
