Don't Trust Me is just one of the 5 group gifts out by Elven. Snatch the tag and grab the gifts before they are gone (think they are left over from Xmas). The outfit comes with several pieces. It comes with top, shorts, pasties, belt, necklace, bracelet, belly ring, and shoes.
The hair is In Space which can be found in the scribo gift once you land @ Curio. It comes in 3 different colors, although it is tintable like it is here.
The skin is from Panda Punx. It is a freebie she has available on her Marketplace store. It's a shame she is no longer available in-world, but none the less go grab it.
