“Women of the 1600s, from queens to prostitutes, commonly exposed one or both breasts in public and in the popular media of the day, according to a study of fashion, portraits, prints, and thousands of woodcuts from 17th-century ballads. The finding suggests breast exposure by women in England and in the Netherlands during the 17th century was more accepted than it is in most countries today. Researchers, for example, say Janet Jackson’s Super Bowl baring would not even have raised eyebrows in the 17th century.”
