Our good friend Isis Sturtewagen has posted a couple of blog posts on her company blog. The first of them discuss the occurence of medieval bras such as the one discovered in Schloss Lengberg in Austria in 2008 (it’s the same one that everyone keeps re-posting). Have a look at it here.
The second one regards Isis’ reconstruction of a garment of that type; I suspect we will be seeing a lot of the ladies in the company wearing their own in the future.
Also, she has written this post about written sources on supportive underwear.
Update: a couple of really cool new photos!
