What´s about boundless-store? She sometimes offers one character to the clothes.
Also kaiZ has characters and clothes combination sets.
dburdick also have character and cloth sets, but no black one as I can remember.
Ah! Perhaps samildanach? Take a look to her shop also.
Older things that I can remember (for V3) have been from Arki-Store.

Good luck, perhaps it helps
