Wow, 4 skins in one day! Anyway this is the first skin Jen has ever used. It first appeared with Jen's first ever appearance on Pat's channel in the Skyblock Let's Play and was used a little bit more afterwords. This skin was used before Jen even had a channel and looks very different from her other 2 skins. These are the only images of it in-game that I could find. There are also a couple remakes of this skin on Planet Minecraft. Enjoy!
