Hi Midhun, 

 This person with the userid NAir is a retarded muslim whose earlier username was some sultan. He is a retarded muslim who eats pigs and talks shit about Nayars here. Please gather all the help possible to do something against this pest. 

 Mr muslim Nair,   

 That dress you mentioned is a general attire and not the traditional dress of nair women. 
 This is the traditional attire worn by Nair woman - http://farm6.static.flickr.com/5202/5229544264_b2eac46e08.jpg. 
 The muslims way back 100 years used to walk naked. Hence they were forecefully made to wear burkha late onwards.
