I'm always bragging about the corset work of Anastasia von Teaserhausen, and with good reason. Anastasia taught a class on corsets through All-Star Burlesque last Saturday. She really knows her stuff when it comes to corset construction. She discussed the differences between fashion corsets and costume corsets, what classifies as a corset and what doesn't, what one should expect from a corset, and how to upgrade fashion corsets so they last longer. It was a wonderful class. When I get a moment, I'm going to upgrade a beautiful corset I purchased from Frederick's of Hollywood that fell apart the first time it was worn.
(If you'd like to contact Anastasia, shoot me a comment. Her website is being revised so I'll help you get in touch with her.)
