Achkan

Achkan (Hindi: अच्कन, Urdu: اچکن) is a long jacket worn in South Asia, and together with the Sherwani, is traditionally associated with the Northern Indian, and especially with the Muslim aristocracy. 

The Achkan originated in Central Asia and was court dress of nobles of Turkish and Persian origin in the Delhi Sultanate and Mughal Empire, before being more generally adopted in the late eighteenth century. It is long-sleeved coat-like garment, worn close to the body, reaching down to the knees or even lower, and buttoned in front-middle. 

It is long-sleeved coat-like garment, worn close to the body, reaching down to the knees or even lower, and buttoned in front-middle. It can be distinguished from the sherwani by the fact that it is often made from lighter, finer fabrics, and is generally unlined. 

It also gave birth to the now known Nehru Jacket, which is a shorter form of the achkan.
