These are traditional dresses from the Pashtun region of Afghanistan, dated between 1930-1970. I think it’s interesting that technology and styles changed so little in Afghanistan between 1930 and 1970 that it’s difficult to tell when it’s from. A 1930s dress from North America would never be confused with a 1970s dress. They’re sewn both by hand and machine, and cut mainly on the square. Cutting on the square is common in alot of folk design. I’m not sure why, but I imagine that it was both to conserve fabric and to reduce the complication of the pattern. I still like cutting things on the square, for exactly the same reasons.
