While browsing through eBay, I found this lady's auctions:
shop.ebay.com/imahorsenut/m.html?_nkw=&_armrs=1&_from=&_ipg=
She seems to be selling a few different Moresca things quite discounted, including several bodices. They're all size XL. Her feedback score is 100%.
They don't fit me, but I figured I'd throw them out there in case someone else is interested.
