Really good black skin is not easy to find in Second Life, but so far what I have seen, Glance Skin, created and owned by Joakim Asbrink, managed to create black skins that are about as realistic as possible. The face is so nicely detailed and the body part is as greatly detailed. Joakim is known for her very detailed skins.
They come with 7 different make ups: 1.Alek - Attention, 2. Alek - Metallic, 3. Alek - Red, 4. Alek – Angel, 5. Alek – Black, 6. Alek - Colour and 7. Alek – Blue
The price per skin is 999 L and for a fatpack which usually contains 7 different make ups, the price is then 4500L.
