The Daily Mail has a short article on the undergarments found in Lenberg Castle which includes pictures of one of the bras and a pair of underpants. Finally something in English!
This is a really interesting find and from what I can tell a paper should be included in the next NESAT with more details about the garments. From what I have been able to find so far, the bras and underwear date to the 15th century and look quite a bit like their modern counterparts, save being made in linen. It does explain how one would be able to get the high-busted look that was so popular at the time. Fitted and supportive gowns are one option, but something about that approach has always bothered me. It seems like a small undergarment with shaped cups that is laced down the waist, like the one shown at right, would work better. And don't even get me started on the whole "women didn't wear panties" thing. A man must have come up with that one.
