I rented a crazy Gothic XXX.  What the hey, I'll try just about anything once.

Are there any Gothic providers in SD or even the LA & Riverside area?  NOT just the ink and/or metal, but the whole look.  There isn't a search engine (yet) for this type of request.

Isabella is the closest provider to Goth that I've seen on the 'net.  I have no personal experience to relate but she has some pretty good reviews.  

Good Luck.

Check out Mary Jane (aka Grace...aka Sweetsluttymee). she has a serious Goth streak although I think she presents a more "normal" look when providing. I'm sure she'd be happy to oblige your request.
as another plus, she's one of the friendliest providers here.
