Rarity black rubin dress

Geesh, I couldn't wait any longer, I have the idea for this dress for a long time now in my head and just finally wanted to finish it!
I call it "black rubin" ...yeah, maybe not a very original name.
But it was so much fun to design this dress for her. X3
I hope you like it, and that I also can finish some other pictures soon. ^^
