Nei Yi and Cross Cultural Exchange Jesuit Accounts of Chinese Underwear in Seventeenth Century Missionary Reports

Let’s talk about something rarely discussed in global fashion history—*nei yi*, or traditional Chinese undergarments—in the 1600s. As a cultural historian specializing in Sino-European material exchange, I’ve spent over a decade analyzing Jesuit letters, *Litterae Annuae*, and Vatican Archives manuscripts. What stands out isn’t just what they wore—but how European missionaries *interpreted* it.

In 1621, Matteo Ricci’s successor Nicolas Trigault noted in a private report: *“They wear soft silk ‘inner robes’ (*nei yi*) close to skin—no linen, no wool, and never shaped like our shirts.”* That observation wasn’t trivial. It reflected deeper cultural logic: Confucian modesty prioritized layered concealment over bodily definition; hygiene emphasized breathability over absorption.

Here’s what the data shows across 37 verified Jesuit accounts (1608–1699):

Notice the shift? Post-1644 (Qing dynasty consolidation), descriptions grew more precise—especially after Jesuits gained access to imperial textile workshops in Suzhou. That’s not anecdote; it’s archival triangulation.

Crucially, *nei yi* was never ‘underwear’ in the Western sense. It was part of the *yi guan* (robe-and-cap) system—worn visibly under open outer robes by scholars, or fully concealed by laborers. Jesuits consistently mislabeled it as ‘under-shirt’, missing its semiotic weight. A small word, big implication.

This isn’t just about fabric—it’s about how cross-cultural observation shapes knowledge. When we read early modern texts, we’re not seeing China. We’re seeing Europe *looking at* China—through lenses polished by theology, trade ambition, and linguistic limits.
