A sari or saree or shari is a female garment in Inia, Pakistan, Bangladesh, Nepal, and Sri Lanka. A sari is a strip of unstitched cloth, ranging from four to nine metres in length that is draped over the body in various styles. The most common style is for the sari to be wrapped around the waist, with one end then draped over the shoulder baring the midriff. The sari is usually worn over a petticoat (pavada/pavadai in the south, and shaya in eastern India), with a blouse known as a choli or ravika forming the upper garment. The choli has short sleeves and a low neck and is usually cropped, and as such is particularly well-suited for wear in the sultry South Asian summers. Cholis may be "backless" or of a halter neck style. These are usually more dressy with a lot of embellishments such as mirrors or embroidery and may be worn on special occasions. Women in the armed forces, when wearing a sari uniform, don a half-sleeve shirt tucked in at the waist.
