I rarely do back to back images to post here featuring the same character, but there is special reason for this one (of course see my blog for a nude variation).
Earlier today on Cartoon Network I saw a Scooby-Doo animated 'movie' called "FrankenCreepie"
In it, Velma inherits the estate of her long lost uncle in Transylvania... Pennsylvania (where some Transylvanian immigrants moved to long ago ). Without ruining it for those who haven't seen it, while visiting her uncle's castle she comes to take up his esoteric scientific ways, even going so far as to adopt a wardrobe more fitting her new role (see the screencap above).
Note that that screen cap is from the actual movie, and it shows that the 'real' Velma actually does have quite a curvy figure underneath that bulky sweater and skirt (although not as full figured as I depict her ^_^).
So inspired by that image, I came up with this (although I guess my version is more into Magic than Weird Science).
