I would appreciate any links for places that sell rubber bondage dresses, and I mean the kind where the wearer's arms are either trapped inside the dress or bound somewhat seamlessly to the back....giving the illusion that the wearer has no arms at all.
That is...if such dresses really exist outside of stories.
The baroness really doesnt do bondage stuff. You best bet will be Demask or having it custom made, Simon-0 does some great work, possibly polymorphe or cocoon.
