The blouses that women in India, Pakistan and Bangladesh wear are a midriff baring top worn usually with saree or lahenga. The blouse is cut to fit snugly to the body. Indian blouses usually has low neckline and are cropped to expose the navel. Since, sarees are generally worn in humid and hot summers, the short length of the blouse and the big neckline makes the heat bearable for women. South-Asian blouses are either buttoned in the front or at the back to make it easy to wear. Blouses are ordinarily made from an extra piece of material attached to sarees in order to make a matching blouse. However, blouses need not be matching in colour to be worn with a particular saree. The designs for blouses have evolved from what used to be a bare necessity to what it is today, an item of clothing that requires much thought and precision before it can be worn.
