While discovering bras from the 15th and 16th centuries may seem completely irrelevant, it actually tells archaeologists and historians something they didn't know — yes, that women were wearing bras then.

While the archaeologists "viewed it as impossible that something like this would have already been worn in the Middle Ages," they have apparently proved themselves wrong. [Spiegel]
