Batik is an Indonesian technique of wax-resist dyeing applied to the whole cloth. This technique originated from the island of Java, Indonesia. Batik is made either by drawing dots and lines of wax with a spouted tool called a canting, or by printing the wax with a copper stamp called a cap. The applied wax resists dyes and therefore allows the artisan to colour selectively by soaking the cloth in one colour, removing the wax with boiling water, and repeating if multiple colours are desired.

The national costume of Indonesia is the national attire that represents the Republic of Indonesia. It is derived from Indonesian culture and Indonesian traditional textile traditions. Today the most widely recognized Indonesian national attires include batik and kebaya, although originally those attires mainly belong within the island of Java and Bali, most prominently within Javanese, Sundanese and Balinese culture. Since Java has been the political and population center of Indonesia, folk attire from the island has become elevated into national status.
