Until the late 19th century, young Western boys and girls often wore the same attire: a dress. Unisex infant clothing made changing diapers easier and simplified the passing of garments from one child to the next. When a young boy had reached an age at which he could begin to train in manly pursuits, he would be dressed in pants rather than dresses. Before the 19th century, his clothing might be simply a miniature edition of adult wear. During the 19th century, men wore long pants and boys wore short pants.
