#9. Dresses for boys
Before the 20th century, and Until as late as 1940 boys wore dresses until they were 5 or 6 years old. After that, they’d graduate to shorts, then to long pants, and over the next decades that transition happened earlier and earlier (and boys stopped wearing dresses at all). Similarly dresses are easier to put on babies and toddlers than pants, and it’s easier to change a diaper on a child in a dress too.
