Shalwars are trousers which are atypically wide at the waist but which narrow to a cuffed bottom. They are held up by a drawstring or elastic belt, which causes them to become pleated around the waist. The pants can be wide and baggy, or they can be cut quite narrow, on the bias. Shalwars have been traditionally worn in a wide region which includes Eastern Europe, West Asia, Central Asia, and South Asia. The kameez is a long shirt or tunic. The side seams are left open below the waist-line (the opening known as the chaak), which gives the wearer greater freedom of movement. The kameez is usually cut straight and flat; older kameez use traditional cuts; modern kameez are more likely to have European-inspired set-in sleeves. The kameez may have a European-style collar, a Mandarin-collar, or it may be collarless; in the latter case, its design as a women’s garment is similar to a kurta. The combination garment is sometimes called Salwar Kurti, Salwar Suit, or Punjabi Suit
