Pashtun culture (پښتون کلتور ) is based on Pashtunwali, as well as speaking of the Pashto language and wearing Pashtun dress. Pashtunwali and Islam are the two main factors which make the baseline for the social behavior in Pashtun society. Pashtuns are traditionally strict and conservative regarding the preservation of their culture. Being the worlds largest tribal ethnicity, Pashtun society is guarded by a code of common rules, customs and social behaviors, known collectively as Pashtunwali. The code is based on personal honor and promotes courage, self-respect, independence, leadership, justice and hospitality. One of the trademark and historical headwear of Pashtun men is an adorned turban wrapped tightly around a hat with one of its ends loose over the shoulders, a sure sign and recognition of a Pashtun. the turban itself has been a symbol of pride and the center of many Pashto proverbs. However, it should be mentioned that different tribes have different types of turbans unique to them, as such tribal styles have been persevered for centuries. They are worn in everyday life by male elders, adults and tribal leaders as sign of status and respect. The common turban comes in a spectrum of colors with unique striped patterns. These styles are uniquely associated with Pashtuns throughout Central and South Asia. However, other Afghan ethnic groups have also however adopted the Pashtun turban style. Another common headwear of Pashtun men is the Pakol hat, which is a soft rolled up flat wool hat, that is worn on the head and worn like a beret. It comes in a variety of earthly colors and is used to keep the head warm, although this isn't a traditional headwear and was adopted in the 19th century, it is worn by many of them today in everyday life. Traditionally modest, Pashtun women when in public, or when visiting cities or in the presence of men, have observed the Burka, a garment worn by some Muslim women around the world. They cover themselves with burka from head to toe, whilst leaving latticed slits, or nets to see through.
