Sherwani (Hindi: शेरवानी, Urdu: شیروانی) is a long coat-like garment worn in South Asia, very similar to an Achkan or doublet, and is traditionally associated with the Muslim aristocracy of the northern Indian subcontinent. It is worn over the Kurta and Churidar, Khara pajama, a shalwar. It can be distinguished from the achkan by the fact that it is often made from heavier suiting fabrics, and by the presence of a lining.  source
