A sari / saree is the traditional female garment in Bangladesh, India, Nepal and Sri Lanka. A sari is a very long strip of unstitched cloth, ranging from four to nine metres in length, which can be draped 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. Office dress codes, however, prohibit cropped, sleeveless cholis; similarly, women in the armed forces, when wearing a sari uniform, don a half-sleeve shirt tucked in at the waist.
