The grand boubou as a full formal a

The grand boubou as a full formal attire consists of 3 pieces of clothing: a pair of tie-up trousers that narrow towards the ankles (known as a sokoto pronounced "shokoto" in Yoruba) and a long-sleeved shirt (known as a Dashiki in Yoruba) and a wide, open-stitched sleeveless gown worn over these. They are generally of the same colour, and historically were made from silk, but increased understanding of Islamic restrictions on clothing meant the grand boubou is now mostly made from cotton and synthetic cloths made to resemble silk.
