This brassiere has been featured on many websites this week, but it wasn't until I got to Spiegel Online that I found the associated* panties:
"Up to now, there was nothing to indicate the existence of bras with clearly visible cups before the 19th century," writes Beatrix Nutz, a university archaeologist. But now the university is proudly displaying four bras with "distinctly cut cups" dating back to the 15th century.*Addendum: "associated" by location but not by wearer. See the link provided by Stella in the Comments which indicates that the lower garment was for a male.
The bras come from a trove of 2,700 individual textile fragments found during archaeological investigations of Lengberg Castle, in the country's East Tyrol region, as part of an extensive reconstruction that began on the building in 2008. Although the garments were first found that year, the discovery was only announced this month.
The bras themselves were reportedly found in a "vault filled with waste" that was perhaps put there when a documented 15th-century addition was made to the castle. Two of them, which are highly fragmented, are described as "a combination of a bra and a shirt," with no sleeves but with lace stitches below to provide extra support. The third, which is elaborately decorated, "looks a lot more like modern bras" given that it has shoulder straps and indications of a back strap. The fourth "resembles a modern bra the most," with its cups "made from two pieces of linen sewn together vertically."
Other finds in the same vault included linen shirts with pleated collars, a pair of completely preserved linen underpants, and a codpiece for a pair of trousers.
