How does a person's clothing tell where he or she comes from?

In all countries, climate, usefulness, and customs (including religion) all influence the way people dress. When people immigrate or move to another country, they sometimes keep their style of national dress as a marker of their ethnicity and culture. In Saudi Arabia, which has a hot, desert-like climate, men and boys wear the thawb, an ankle length piece of clothing, sometimes made of cotton, which is long and fits loosely. Men also wear a ghutra an iqal on their heads a square head cloth with a double circle of black rope or cord to hold it on the head, which keeps them cool. Women wear a long dress with long sleeves, called a jallabia, which covers every part of their body because their religion (Islam) does not permit them to show any body parts. Women in Japan sometimes wear kimonos, a traditional, full-length garment that wraps around the body like a robe, and is secured by a wide belt called an obi, usually tied in the back. In Japan, professional sumo wrestlers are often seen in kimonos because they are required to wear traditional Japanese dress whenever they appear in public. Nigerians often wear traditional Nigerian clothing, both in Africa and when they travel, which is made from lace, jacquard, and ankara, and sometimes tie-dyed. It usually consists of a shirt, long, flowing skirt (that can be tied in different ways), and a headpiece for women and cap for men. And American-made Levi's Jeans are worn across the globe by everyone from Americans to Europeans and South Americans, so it might be hard to tell where a person wearing jeans really comes from!
