Sculptured reliefs from the 2nd century BC show men and women with unclothed upper bodies wearing the sari wrapped around their hips and drawn between the legs in such a fashion as to form a series of folds down the front. There was no major change in the costume until the 12th century, when the Muslims conquered north and central India and insisted that the body be covered. Hindu women wear the sari over a short blouse and a petticoat into which it is folded and tucked at the waist to form a long skirt.
