I will tell you this, it is EXTREMELY hard to combine Rit Obsidian top with any skirt besides the Obsidian skirt itself, due to the fact that the tattoos will not match up with the other skirts, there will be a spot on the back of the skirt where the tattoos will end.
It can still be done. My fiance showed me Elite Luxon skirt with Obsidian top and it looked nice, but I wanted to see some others before I bought that one. I know it's difficult to match up, and I looked closely at all skirts before posting my request. I'd still like to see the screenshots.
