Directory of Finnish Piercing Studios - Juhapekka Tolvanen has listed some studios. This used to be updated. Fashion Costumes.org - Contains nearly any kind of information about costumes. Recently I found 8 pairs of busk from the flea market. I already thought that my project will not carry on because of difficulties finding busk from Finland.
Corsets are pretty interesting items of the history of fashion.
At Riga I saw the most fancy one with chrome horns. Honestly, the cream white gorgeous had at least 10 of them.
