I thought something said the clothing was by Rhiannon, who often works with Danie and Marforno so that would seem consistent. However, I can’t recall where i saw that so it may be wrong.
Well, I’m not 100% certain, but I think that the product page initially listed “LadyRhi” as the creator, who I always assumed to be Rhiannon for the reason you just stated :D
LadyRhi = Rhiannon = same Person just so that you know one name is the name she use at Renderosity the other she uses here.
I just checked the read me and one of the file paths is \Runtime\Textures\Rhiannon\Katya\ so its defiantly one of her’s so you can go searching on both names to find her other products but I think she uses the LadyRhi here at Daz more
