The pallu of the sari is often made with extra length. This is meant to be cut off and made into a midriff-baring blouse (called a choli in North India). Blouses may be of contrasting colours as well. The sari is draped over the blouse, covering the front and one sleeve completely. The other sleeve is exposed and shows enough of the colour and design of the blouse to create a pleasing effect in combination with the sari (whether matching or contrasting). Many styles are used today, including halter, open backed and closed backed. They can be embellished with embroidery and beadwork to suit personal taste or traditional style.
