The existence of Pakistan as an
Islamic state since the
1956 constitution has led to the large-scale injection of
Islam into most aspects of Pakistani culture and everyday life, which has accordingly impacted the historical values and traditions of the
Muslim-majority population. Marriages and other major events are significantly impacted by regional differences in culture but generally follow
Islamic jurisprudence where required. The national dress of Pakistan is the
shalwar kameez, a
unisex garment widely-worn, and
national dress, of Pakistan. When women wear the shalwar-kameez in some regions, they usually wear a long scarf or shawl called a
dupatta around the head or neck. The dupatta is also employed as a form of modesty—although it is made of delicate material, it obscures the upper body's contours by passing over the shoulders. For Muslim women, the dupatta is a less stringent alternative to the
chador or
burqa. ==Languages==
