What is mentioned as a southern fashion seen in the Lepakshi frescoes in the context of women's clothing in the Decani School of paintings (Ahmadnagar)?

Long scarf passing round the body

Answer:  Long scarf passing round the body
The paintings of Ahmadnagar, women wear a modified northern costume, and only a long scarf passing round the body below the hips is a southern fashion, seen in the Lepakshi frescoes.

The earliest examples of Deccani painting are in a volume of poems, celebrating the reign of Hussain Nizam Shah I of Ahmadnagar (1553–1565). Most of the 12 miniatures that illustrate battle scenes are of no artistic interest, but interestingly, those depicting the queen and her marriage delight us with gorgeous colours and sensuous lines. The woman represented in it belongs to the northern tradition of pre-Mughal painting, which was flourishing especially in Malwa and Ahmedabad during this period. The women in the paintings of Ahmadnagar wear a modified northern costume with choli (bodice) and long braided pigtails, ending in a tassel. Only a long scarf, passing round the body below the hips, is a southern fashion, which is seen in the Lepakshi frescoes. The palette is different from paintings of northern manuscripts, coming largely from the Mughal atelier, as they are more rich and brilliant. Paintings of the Deccan have similar characteristics. The high circular horizon and gold sky have Persian influence. We may see the debt of all Deccani kingdoms, which they owe to Persia for their landscape idiom.
