Photographs of dancing girls/courtesans taken during the late 19th/early 20th century demonstrating regional costumes. Lots of anklets:)
Pic 1 is of a Tamil dancing girl (I think the sari was probably a nine yard and the pallu is belted at the waist and allowed to fall); Pic 2 maybe from Bengal (Calcutta was mad for nautch in the 19th century but many dancers came from afar, often the costumes are Northern - though you can count on Kalighat painters for a local flavour), again Pic 3 could be Bombay or Calcutta given the sari and blouse and they do love shoes, Pic 4 is from Maharashtra given the sari style. Pics 5 to 7 are all possibly of Northern/Lucknowi nautch girls. The Lucknow nautch girls deserve an entire post - their photographs indicate that they were every bit as alluring and sassy as suggested by this paper.
