This style of sari draping is common among all the castes but the way of draping differs according to the region and topography as well.For example, Brahmin women wear it in a particular way which is called as brahmni on the other side aagri people from the raigad district wear it in a knee length fashion is called as 'adwa patal' whereas with a small variation the kunbi or the farmer women of raigad district and some parts of ratnagiri as well wear nineyard which is called as "uprati" .The name uprati means up side down which is because of some folds while draping the saree are up side down. One of the special features of adwa patal and uprati arethat these sarees are draped without tying knots but still the saree is very tightly draped. On contrary to this women from rural Puñe and Satara Ahmed Nagar or Kolhapur, wear it to the ankle length which is very popular and one of the best types of wearing it.

The decorative ends are then draped over the shoulder and the upper body or torso. Sayali Badade, an HR executive said, "A woman who wore a Nauvari was always looked upon with respect. The reason being both the shoulders of the women are covered, and it makes for a completely traditional wear. The style was originally started and popularised from the Peshwai reign".

On the contrary, some consider the Kasta sari has fallen out of favour currently. It is considered far too revealing. It is rarely seen in the cities. This type of sari is regularly made fun of in films, portrayed as some sort of “sexy” garment, meant to titillate. In reality the Kasta sari embodies freedom for women. In a way it is similar to the dhoti as it allows leg movement and the ankles are left free. But today the Kasta sari will only be considered decent if distorted to hide every inch of a woman’s body.
