Well one (the darker one) is Naomi Campbell skin tone of SeraSims, the other I dont remenber who she is but I am sure its from another SeraSims celebrities Sims.
That is the underwear with the red shoes from PAF mesh recolors I done with the Transparent sleevesless (open and closed) shirt with micro black skirt outfits.
If this is too risky ... sorry I just think its not exactly "adult" but if its deleted or move there I understand, I just make it avaible because even if its easy to get using Bodyshop (just needs to delete the skirt and shirt alpha but I also made the texture of the skirt and shirt black to reduce size) I seen people saying Bodyshop crashes.
