Caverna Obscura is a Second Life skins designer. You can purchase various outfits, shoes, boots and other items to add to the avatar you use in the Second Life universe. They have created a skin called Demonia Avatar.
Demonia Avatar by Caverna Obscura is an almost full-prim complete avatar, with the exception of the textured boots base for the boots, and no hair.
The rest is all included: shape, skin, ears, horns, tail, wings, body spikes, bra, thong and boots. Made of sculpted prims, with just a few normal ones thrown in here and there.
The boots are scripted to resize so that you could modify them and wear them with any other outfit too, with your own shape.
All prim items are copy/mod so you can resize them and try to fit any shape.
