These are 16 new textures (some racy and delicate!) for the Nyx Midnight Gown by Rhiannon for La Femme (you will need this to make the textures work)

Since it's a dynamic gown, it will flow with your poses--of all the dynamic garments I have used, this one actually will do sitting poses! You may notice that the straps will "float"--and I often will use the Morph tool (that looks like a finger) to "Push" the straps down in place. The collar is constrained to la Femme and you may notice the inner edges curve in a little, which makes the collar on Rubies have the design skim the inner edge. The morph tool option "Iron" will smooth this out, though it takes a light touch with the iron.
All the textures work well in both Firefly and Superfly--Superfly has a little more sparkle, that is all. Thank you for checking it out!
