The dress is just one of the many outfits and skins available as group gifts @ Jstylez. In the package you can get both red and black dress.
The hair is from Analog Dog.
The skin is from Angeldust. The skin is part of the new 30 day or under package she developed for the new residents. But for this week only it is also available in the lucky dip for anyone that wants to go diving for it. And you only have to wait 1 minute between trying to get the item.
