In much of Europe and the Americas during the 19th and early 20th centuries, shorts were worn as outerwear only by young boys until they reached a certain height or maturity. When boys got older, typically around puberty, they would receive their first pair of long trousers. This produced the perception that shorts were only for young boys. Because of this, men would not wear shorts to avoid looking immature. Women tended not to wear shorts in most cultures, due to social mores: they were expected to wear dresses, or skirts and blouses.
