Indian women have traditionally worn saris that partially cover the midriff, especially South Indian women. One of the styles of saris is bare midriff. The gap on the midriff between sari and the choli presented the elegance of a woman's body and suggests a feminine strength. It also makes them look attractive, is sometimes used in Indian traditional dance as it allows a flexible movement. Both men and women have bare midriff while performing the classical dance. It has also become a part of Bollywood culture. A less likely cultural explanation could be that in ancient Indian scriptures, the navel of the God Vishnu the Protector is considered to be the center of the universe and the source of life. From his navel a new world of the future emerges. A woman is considered as creator of life and source of Shakti, hence the bare midriff also symbolizes free flow of cosmic energy. This has been depicted in many ancient Indian sculptures as a lotus emerging from the navel on which God Brahma the Creator is seated. Due to this the midriff is set to be left bare in a sari. Another more practical reason could be the hot tropical climate of India. Rathi Vinay Jha, director general of the Fashion Design Council of India told, ""The bare midriff keeps you cool"".
